I love the fact that the part showing Kelly Johnson, if you look at the bottom of the blackboard it says "Area 51". I thought that place doesn't exist. ha ha...good to know that a machine that is almost from another world, was tested at a area that doesn't exist.

"Area 51" shows up on maps. It's just a grid marking from an old military survey. everybody knows about area 51. The Soviets have been overflying area 51 with satellites for some 40 years about every 96 minutes. I think the real secrets are buried under a corn field in Iowa or on some remote pacific island or somewhere like that. Area 51 is not really that big a deal. I think the government is laughing about it as a tool of mis-information and mis-direction myself.

that man named Kelly Johnson was a great man and even more, a great engineer.

that aircraft is indead the best aircraft ever built

[TJDOZIER1]

Yes he was, I met him as a boy, my dad worked with Kelly Johnson on the F-104 Starfighter flight test program.

@elkranch ..The B-2 Spirit, one of the darkest projects in USAF history, was flight tested at EdwardsNorth...not Area 51......Peace

"The two engines produce more thrust than the engines of the queen mary".. Well fucking stick a couple on the bow! Shit.. Then we'd have a boat!

Nice

SR71 can photograph the plate number of a car while flying at 80,000 feet with a speed of 2,000 miles/hr that gets it from NY to London in only 1hr and 55min! A true feat of engineering.

@Heathh49008 Yes, there wasn't much speed left after Mach 3.5 in terms of metallurgy. I believe the quartz windshield might have been running near its limit as well. It was a highly tuned machine running at the limit...

[Heathh49008]

@beeroosterm The metallurgy is another factor as well.

I understand why people would like to think it was faster... there is wonder and romance in those thoughts.

If it makes them feel better, SCRAM jets and new materials can make those dreams a reality.

If only we had Kelly Johnson....

[beeroosterm]

@Heathh49008 The Blackbirds and their variants using the J-58 engine were limited by the compressor inlet temps, with a maximum of 427 degrees Celsius. Anything higher would soften the blades. The fastest I ever read about these things going was in the area of Mach 3.5 for a very short time in ideal conditions - and under great stress...

[beeroosterm]

@ytvvtyytv Nope. Sorry - you're wrong. The Mig-25 cannot sustain Mach 3.2 without destroying the engines, and in fact, the scenario you propose was tried and failed miserable. There's a You Tube video with a former Mig pilot who describes trying to shoot down an SR-71 with a group of Mig-25's and failing miserably. Too fast, too high, and their technology was for shit.

[beeroosterm]

@harryfmk Actually, they take off with a really light load of fuel to keep airframe stresses to a minimum in case they need to land quickly. Leakage is relatively minimal. They'd take off with a light load, run it fast for a short time to get some heat in the airframe and seal up the tanks and then top it off.

@OntarioRailfan1996 wrong. thers no connection between the arrow and the blackbird. other than maybe some enginners and designers. the technology of the two planes are like night and day. i will agree that the arrow was an advanced fighter/ interceptor, and one of my favorite planes, but saying the blackbird was based off of it is not correct.....
