SR-71 Blackbird

lol it must be fast its top speed is highly
confidential and this planes over 45 years
old imagine what they made since then.

ramennoodlelover....The SR-71 top speed is its cruise speed..under the right conditions of air temp and engine flow performance, the top speed =cruise speed could reach as fast as 500 KEAS =equal to about Mach 3.5....

no its stop speed was mach 3 not mach8

I heard its top speed was mach 8

Actually, some parts are corrugated to allow for heat expansion, not because of air pressure.

Oh, and as long as we're making stuff up, little hamsters on wheels power the engines.

put those engienes on the scc lol

cool cool, thanx man

the airframe covering has to be built slightly loose because the pressure of mach 4 is so great that if it was a tight fit it would probly crush

if you think you can go from america to russia in 30 minutes when flying at 3500 Kph I suggest you should watch a map of the world !!


You do realize Russia is just off the coast of Alaska?

Search for "Era" music here at Youtibe, and you´ll find what youre lookin' for.

the one at duxford hangs from only a few wires
so its obv not that flimsy.

Please, can someone tell me what music is it
just awesome music and clip

the exact spped of the jet is classiflyed my
friends a engineer at pratt and whittney i
asked him and alot of his fellow engineers
at the 50th anaversary.

you dont need to spell to be good at math
crass nub.

Yes the SR-71 leaks on the ground but they aren't THAT loosely built. Over half of the planes maximum take-off mass is fuel, it has plenty. And loose is a very vague term, and having been able to be up very close and actually touch an SR-71, trust me it's not by any means loose. Continual heating and cooling causes it to leak, flying Mach 3.3 tends to get pretty hot!
