3.5 MILES IN 10 SEC.

[laxinitup62]

mach 2 ? i thought the x-15 reached mach 6.5

[Crashman2]

@laxinitup62 CERTAINLY! THIS FILM IS JUST THE FIRST TIME IT EXCEEDED MACH 2! AND I HAD TO TAKE CERTAIN LIBERTIES WITH THE TITLE BECAUSE OF THE MUSIC!  I CLAIM ARTISTIC LICENSE! NOW- please show me YOUR X-15 Video!

[Crashman2]

@laxinitup62 You're right. Mach is just math at those speeds and altitudes. Record speed was: Flight 188 3 October 1967 4,519 mph (7,273 km/h) 19.3 miles (31.1 km) Up there where the air is so thin, you can get big Mach numbers easily because the atmosphere is so thin that sound goes s-l-o-w-l-y...instead of Mach 1 being about 730-760 MPH on the ground on a "Standard Day". Scotty was just the FIRST to take her over Mach 2, in 1962. Look up "X-15" in Wikipedia.

[1MtnBoy]

AWESOME ! from one X-15 junkie to another thanks for posting this !!

[Crashman2]

@1MtnBoy  YOU are why I do this! THANKS, man!

[Crashman2]

From one speedster and airman to another... we subtly recognize each other. FLIGHT is my Life...  THIS is my song... The Titanium Shockwave of our passage makes the groundhogs wonder.... For they will never know The Terrible Joy of The Sky and PURE SPEED! "Yea, though I walk thru the Valley of Death, I will Fear NO Evil- Thy Mighty Pratt & Whitneys comfort me, my G/pressure suit Inflateth; For I am at 60,000 ft. and CLIMBING... " (the SR-71 Pilot's Psalm)

[1MtnBoy]

@Crashman2 thy mighty pratt & whintneys,..................in­flateth ??, omg, laughing so hard im gonna choke on my coffee !! I needed that this morning, thanks !!

I am a huge X-15 / Shuttle enthusiast. I'd love to see more VIdeo's on Scottie and this beautiful beastie !

[Crashman2]

@1MtnBoy More X-Vids? I got real sad about it all when he went in in his Cessna 210. I'm rated to fly that airplane, even a weenie Private Pilot/Complex Aircraft rating like me, and a lousy WEATHER FRONT took down Scottie. Why? WHY? There are NO answers! I'm just glad we still have Chuck and Bob Hoover with us! The Sky Gods claim Their Own....and always FAR too early!

Part of me will NEVER stop weeping for COLUMBIA and CHALLENGER, too. They too gave their young LIVES pushing us all HIGHER!

[1MtnBoy]

@Crashman2 well............you can look at it like this: " He went with his boots on" !!

from what I read it looks like the Cessna broke up midair ? the article said the plane was found in three large pieces about a 1/4 mile apart.

[Crashman2]

@1MtnBoy OK, as a 37-yr Private Pilot I can tell you this. NOBODY flies thru thunderstorm cells and lives, not even airliners. A T-storm cell has the energy of about a 10-kiloton nuclear blast. He EITHER A) penetrated the storm cell and emerged as wet scrap metal, OR B) tried to get low and dodge around under it, where he could see. This practice is known as "scud-running" and has killed many a lightplane pilot, as well as Frank Tallman, the greatest movie stunt pilot who ever lived. I say B.

[robertosygal]

why you just dont put 2016km/h

3.5 milles in 10 seconds

3.5*1.6= 5.6 km

5.6/10= 0.56km/s * 3600 = 2016km/h and its not that fast as you put it...

[Crashman2]

@robertosygal BECAUSE- none of his instruments were calibrated in metric, your math is TOTALLY WRONG, and IT'S THE NAME OF THE DAMN SONG, not a mathematical exercise? Why don't you just read the OTHER comments on this that have been voted WAY about yours? 3/5 of a mile IS 1 Km, dork!

[005658able]

Gave a new meaning to the term "breaking wind" What a ride!

[mfsxlover]

@Crashman2 i mean before he took off(he looks rather tired)

[Crashman2]

@mfsxlover Yeah, he had to be there by like 3 AM for the 4-5AM fueling, so why bother to try to sleep- you'd just think about taking ultra-thin tanks of 2 really exotic rocket fuels that explode on contact up to 70,000 feet and hit 1500 MPH doing it, then land ON SKIDS if your rudder jettisons right....... *I* always relax real well just before doing that for the first time in history. They were racing the Air Force to set records, and like NOBODY slept except on a bench in the hangar...

[spencnaz]

@Crashman2 The fuels of the X-15 weren't hypergolic.

[1MtnBoy]

@spencnaz LOX and anhydrous Ammonia......................p­ressurized from a liquid helium tank, look out !

[mfsxlover]

at 2:42 someone's forgot there coffee

[Crashman2]

@mfsxlover At those altitudes a cup of coffee would flash into sticky vapor in 1 second. Boyle's gas laws. It's happened. You never unseal a Thermos bottle of coffee that was sealed at ground level in an unpressurized airplane above 2000 feet. The white vapor you see releasing is pressurized tanks of rocket fuel and LOX boil off freely in the climb-otherwise they'd explode at altitude if they couldn't vent. Briefing over.

Go and sin no more, for the sky will crush thee.

[1MtnBoy]

@Crashman2 thats actually what they called the "Pre-cool" cycle Gents. (49 sec mark) tanks were filled, sealed and pressurized and continually topped off from the NB-52 aux tanks. then just before launch pilots would start the APU's and then pump fuel (LOX & Ammonia) through the engine turbo pumps to bring all the parts down to the Cryo temp of the fuel(s) and stabilize before ignition. LOTS of LOX and Ammonia vented out the rear, lol. GO Scottie GO !

[Crashman2]

@1MtnBoy I bow before Superior Knowledge. But it was still venting pressure-just for more purposes than I thought. Forgot about old 1967-metals crystallizing to glass when down at Cryo- temps. And the fact that she was basically still fueling while attached to the BUFF. APUs are the least appreciated part of any airplane, but they'll save your ass! Thanks for the Wise Words! At least one Orbiter suffered a Main Engine Shutdown because of crap in the Turbo-Cryopumps.. It made MECO, tho!

[1MtnBoy]

@Crashman2 LMAO.thanks but I am no expert ! just a huge fan with a few books, pic's and family that worked for JPL & Lockeed back in the day. I know just enough to be dangerous. from what Ive learned the ammonia propellant tank was filled at -35F and sealed preflight. the LOX tank was filled, then both tanks were Helium pressurized to 48psig. the LOX tank was allowed to vent as was the 500 gal. aux LOX tank on the Buff this kept the temp to about -300F. LOX was constantly topped off.

[Crashman2]

@1MtnBoy Yeah. I'd hate to run out of LOX and have to glide home on 2 razor blades and a chine. The helium ullage idea was WAY ahead of its time. But so were fuel tanks that exploded spontaneously with the force of a 1,000-lb. bomb. I'm reading the history of the ME-163 Komet, that used hydrogen peroxide and some other God-awful hypergolic explosive for fuel. Sometimes they would just blow up on the ramp, and they couldn't find anything of one pilot but his watch. Vaporized, I guess.

[musicislifessc]

Chuck Yeager where are you!

[Crashman2]

@musicislifessc He's here. See my SKY SPIRIT video, same CRASHMAN2 Chan.

[RyanFromUltrasound]

Its actually 4.2 miles in ten seconds but who cares. Awesome song, awesome footage.

[Crashman2]

@RyanFromUltrasound  Heh- artistic license for the song. He had to slow down to let the chase lanes catch up while he jettisoned his lower rudder to LAND ON SKIDS!

[Fourteen88SoCal]

me next me next!!!

[skipplet]

Perfect song for this video.

[Crashman2]

@skipplet I was racking my brains.... and then remembered that you can't go wrong with vintage J. Airplane. Much to my surprise, it was PERFECT!

[gebass6]

@Crashman2 Naw!The best song would be "Zap" by Eric Johnson

[Crashman2]

@gebass6 DO IT! Take my video edit and switch the track - or Mute my sound and play yours- . It''ll synch

and probably be better! PERMISSION TO STEAL VIDTRACK EDIT 100% AND RE-MAKE GRANTED! Just

mention my nick in the descr. and tags- that's all I ask. Credit yourself in the last frame as full co-maker! I

collaborate all the time and the vid comes out 4X better. Watch my vid "PROUD AND GLORIOUS"

below-where my co-maker is a Japanese pro CGI maker! TOGETHER WE STEAL FOR PERFECTION!

[fluffycat087]

X-15....wow......wow then......wow now.

Saying that the Scuttle glides kinda quick!!!!

Thanks

[Crashman2]

@fluffycat087 You are most welcome.

[GrantasaurusRex]

cool amazing what they did.

[Crashman2]

Mocow to the Moon...

[mufflerbearin]

holy shit it was on the edge of space. he buried the mach gauge broke the needle on it

[suprafrase]

judging by the footage from the rear facing camera, it looks like quite a wild ride. awesome footage

[AeroSail727]

This video is top notch. one of my favorite aircraft with quality music. What more can I ask for?

[Crashman2]

@AeroSail727 Thanks! How about .... 36 MORE vids on aerotopics? Same chan, same host server? Now if I could just get rid of the Ads... or at least make them all funny or about planes...

[xoio]

3.5 miles in 10 seconds?

The X-15 attained a max speed of 4520 mph = 1.255 miles per sec = 12.55 miles in 10 sec approx ... A bit more than 3.5 in 10 sec.

Travelling at Approx mach 2 = roughly 1350mph = 1980ft per sec or 0.375 miles per sec. 10 (secs) x 0.375 = 3.75 miles = roughly the fingure you mentioned above.

Cool vid though

Thanks :-)

[Crashman2]

@xoio All you mathmaticins- IT WAS JUST THE TITLE OF THE SONG! And yeah, I tweaked it a bit to stay in the "approximate zone!" LOL you guys..... I bust my nuts over these vids and you want the math perfect too? Ain't gonna happen. I plead Artistic License! LOL! Just sit back and enjoy it WITHOUT all your Machmeters, altimeters, and calculators! But that ain't gonna happen either.. there's ALWAYS a few......

[Pepperidge13]

@Crashman2 You owned.

[Crashman2]

@Pepperidge13 Thanks, but give the credit to Scotty Crossfield and Grace Slick, not me. The 2 -visuals and song- just seemed to go together. "Take me from this simple place..." And watching him lose his chase plane in seconds, then up to about 60,000 on rockets, then a turning contrail against the black of Space....to land from Mach 2 ON SKIDS! If he had even trembled the stick up there it would have gyrated and broken up. Funny watching it ditch part of its tail just to land!

[bruhe]

@xoio lol thumbs up for nitpicking with a mega brain :)

[xoio]

@bruhe LOL *takes a bow*

[soyounoat]

@xoio: Yes, but the song playing in this vid is 3/5 of a Mile in 10 Seconds (Jefferson Airplane live from Bless It's Pointed Little Head). Nice one Crashman2!

[scpmr]

rocket with wings

[MzYeLloWbUsRyDa]

how come he switched on the spraying substance before even launching?

[Crashman2]

@MzYeLloWbUsRyDa venting cryogenic propellant ullage as he climbed to release altitude... equalizing cryofuel pressure. Shuttle does this too.....

[VrOOm1337]

You think this is fast... the fastest unmanned rocket sled hit 10430 kph no lie go check it out and research.

[blyndrotor]

@VrOOm1337

Funnily enough I have just been looking at such material.

Check out the sandia rocket sled tests. Very cool stuff.

[manoman0]

...and James May from TopGear with his 400km/h Veyron thinks he's fast.......=D

[JAG03064]

The original designs for this plane are over 60 yrs old, think what's hiddin in the hangars of the skunk works right now...Aurora?..It's plans along with sr 71were on the drawing boards during the cold war...If the X43 is disclosed what do they have that isn't ?!

[kladivous]

Someday I would really love to have the opportunity to try to become the fastest man alive.

[csifan17]

oh yeah

me too xD

[336Torana]

I already am.. well. thats what my missus reckons anyway :(

[J0n3eR4M]

this vid was made on my birthday

[tipou900]

who care..

[etclay00]

199 successful flights; first pilots to see the curvature of the earth.

[CalzLincoln]

You know.....I could use one of those - I wouldn't mind getting up for school 2 and a half hours later than I usually do.

[warwolfii]

Originally the US space program was considering flying into space in a craft along the lines of the X-15. It had a rocket engine in development that would have taken the next X plane out of the atmosphere. The sudden success of the Russian launch of Gargarin forced them to go to Plan B which was the "quick and ugly" method of the rocket/capsule type launch. Once they were committed to that, the X-15 program became redundant.

[AussieGearHead]

Wow someone actually found a video of a successful test of these things. Most of them ended up in bits all over the desert lol ever wondered why the development stopped?? lol.

[EtzEchad]

@AussieGearHead Only one X-15 crashed. It was a hugely successful program. You, on the other hand, are an idiot.

[Lex5576]

Even the landing speed of those things was astronomical. It must have took one hell of a runway to bring them to a stop.

[Crashman2]

Yeah.. the 20-mile-long dry lakebed at Edwards...

[amh5034]

the pilots that flew these bad boys got astronaut wings.

[honalululy]

this is the x-15... it went mach 6... at 300,000 ft

[maciekrogala]

7243 km\h rec speed

[FruityLoopsas]

3,5miles in 10sec = 21miles in 60sec(per minute) = 1260miles in 60 minutes(hour) = 1900km/h

[TheGoogleAdmin]

This isn't Mach 2, according to the Video description it is 1260mph= ~2000kmh

[logic2reason]

depends on altitude. clearly it is not mach 2 at sea level

[italy430]

which is about Mach 2. Mach 1 decreases with an increase in altitude. at sea level M1 is 761mph and at 36,000ft it is 655mph. and considering the x-15 reached over 328,000ft in altitude, M2 would correspond to the 3.5miles in 10 sec, just a bit higher than 40,000 ft.

[kaspariito]

crazy times.. lots of humantesting :D

[csBlaZe97]

@kaspariito and this is the way it should be now.... theres plenty of people who would love to get in one of those things and rip the throttle... I know I would.

[DigiTan000]

"Sir! They've just fired a Lieutenant at us!"

[weenadelic]

@DigiTan000 We'll respond in kind...

[Parahdoks92]

@DigiTan000 Pffhahahha!! Dude, you don't know how much that comment made me laugh! Awesome dude.

[MRKerilx]

you need some balls to do this!

[pieplicht]

a deathwish might come in handy to

[mazda1024]

haha missile man!

[matteomelania]

how to km?i'm italian and i don't speak very well english.. :-)

[Goosemaster]

3.5 miles = 5.632704 kilometers

[Crashman2]

he x-15 reached something like 8200 km/h high

speed

[matteomelania]

thanks

[BobMarkeyUGT]

Fastest speed I can find recorded for it was M6.70, or 4,519 mph (7,273 km/h). That's 2.25 times faster than Scotty flew it. ;)

[suklaakani]

@Crashman2 7274 km/h, 4520mp/h, 2021m/s :P

[AJAnewage]

@Crashman2 dude i really dont think so, unless it was a unmaned plane its impossible

[Crashman2]

@AJAnewage Calculating Mach numbers at hi altitude demands some deep math. The Machmeter shown is correctly set.

[Usafkyle]

Nice Video Is That a B-52 carrying The X-15

[XOROHN]

yea you're right.....thats are two fucking great airplanes!

[Usafkyle]

Woo Hoo!!!

[sixstringmania]

these old videos are great

[XOROHN]

XB-15 Hell Ya! great thing!

[1sgleguyin714]

whats with the crappy music this would have been great with the real audio

[Crashman2]

It's from the time... But I can never please everybody re music. Try muting the sound and play what YOU want! Or better yet, DL this vid and post it again with YOUR music! Who knows, it might be better!

[artglick]

Jefferson AIRPLANE, man. Quite appropriate and a GREAT song.

[enuneko]

where can one find it without music?

[Crashman2]

On YouTube. Search X-15 and "Scott Crossfield".

[elkranch]

Neil Armstrong fly the X-15 pryor to his Apollo mission.....

[wojtasmaster]

X-... Wing?

[Chopin742]

No, it was a rocket with stubby wings and a think triangular tail.

[madgrapho]

I think the X15 was awesome. Thanks to this user we all get to see the crazy stuff some people had the guts to do to allow us to enjoy the modern world as it is today. Oneday the crazy stuff spaceobjects does may change the lives of us all....who knows....do you?

[londongamer]

This is like being sat astride a missle a la Strangelove style, except he's IN it,.. though both have the ability to explode spectacularly. :D

[heymisterderp]

Umm back to reality now. Flying the X-15 took a lot of courage. Nevermind landing it.

[P0werw1se]

Took a lot of courage. If anything went wrong at that speed, the pilot would be a collection of atoms floating around in the mesosphere.

[viper1995]

thats nuthin, the speed of sound can circule the earth 6.3 times in 1 second !!!!!

[P0werw1se]

I think you mean light.

[USAF300]

That would be the speed of light.

[tomxa350]

wtf no it cant. speed of sound is about 750mph. The world is 12000 miles long. cant even do it in 12 hours.

[Chopin742]

No, this thing could circle the speed of sound.  Not sure how long that would take though=)

[Crashman2]

You're right the X-15 was WAAY ahead of its time and its full flight envelope was never explored. For fear of it becoming a satellite...

[jarod2727]

they only retired that about 20 years ago

[heymisterderp]

Great song choice! Five stars.

[AT2puke]

Great video and song... What a combo..

[Delta9prod]

Top video!

[Crashman2]

Thanks! This one was for Scotty, who flew so high and fast it was ALL black... and HELD THAT ROCKET-POWERED BITCH STEADY! And let's shout out for the immortal JEFFERSON AIRPLANE! Same time, same station... THE 60's!

[kobasica]

the x-15 reached something like 8200km/h

[ARhettE]

It reached approximately Mach 6.7

[kobasica]

which is 8200km/h

[JumpShotHero]

Watch the video that shows the damage. CRAZY!

[Goldenballs36]

Almost, it was officially 7,274 km/h.

[BIGGEORDIE70]

Slick, cool video. Thanks

[mackb909]

Isn't the title of this song "3/5 (three-fifths) Of A Mile in 10 Seconds"? .6 vs. 3.5: big difference. Marty Balin even shouts "three-fifths of a mile in ten seconds!" at the end of the song...otherwise, excellent song, excellent vid... Thanks.

[Crashman2]

Yeah, you're dead right on the title of that Jefferson Airplane song. I plead artistic license, based on rough calculations of the speeds Crossfield achieved on climbout.

[Rhenoism]

So they're flying over Woodstock?

[SmiertSpionem]

It takes a special sort of man to fly on big fireworks.

[sundog47]

F-104 chase plane; how cool is that.....

Great video Crashman2 thanks

Sundog

[Crashman2]

I like how his rockets are fired manually one by one by ordinary toggle switches protected by that steel guideplate around the bank of toggles. Glad you enjoyed it.

[cjshull]

Unfortunately the pilot was killed in one of the later missions of the X-15 when an aft thruster stuck momentarily causing the jet to enter a flat spin - when the plane fell into the stratosphere the flat spin picked up speed and the centrifugal force prevented the pilot from reaching his control surfaces, and the plane crashed to earth with the pilot aboard, unfortunately he was of course killed. It's assumed the pilot blacked out sometime during the early stages of the centrifugal force.

[Crashman2]

That was Mel Apt.

[cheyennemesa]

Mel Apt Died while testing an X2, not an X15

[Crashman2]

Correct. Mel had NO previous X-rocketplane flight experience, and his death closed down the X-2 program in 1956. I never said Mel died in an X-15, but the manner of Mel Apt's uncontrolled wildly-rolling bad-attitude re-entry above is basically correct.He did manage to separate his escape capsule but bailed out WAY too low. The X-15 pilot who was killed in a hypersonic spin was Mike Adams in X-15 #3, Nov. 15, 1967.

[cheyennemesa]

Bye the way, that video is ace

keep it up!

[yegnats]

Woah, was this guy flying in subspace?

[Crashman2]

Flying at or above 100,000 feet altitude is considered to qualify you as an "astronaut". The X-15 did this easily - look how the sky is *black* up there. The highest X-15 flight reached 354,200 ft (67 miles) on flight Aug. 22, 1963, flown by Joseph Walker.

[maclarcs]

Space starts (officially) at 100km or 328,083 feet. Still makes him an stronaut (although USAF gave astro wings for flights over 50 miles.)

[Crashman2]

Precise correction, thanks. The FAI does define space as 100 Km or about 62 miles.

[tomterahedrob]

theres an interview of Crssfield on 1970s Tomorrow show I saw when I was 9 or 10.Even then I thought this man is just supremely cool.
