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.

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 :-)

the pilots that flew these bad boys got astronaut wings.

@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!

@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.

[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.

[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.

[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 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!

[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!
