over 6,000mph??? WTF that is SR-71 blackbird territory

^^No planes fly that speed.

It's a test of hypersonic missile.

it's a sled

I am no expert in aviation but didn't nasa test a blackbird mule at that speed in 1989? or was it that other thing they call TR-3B? anyways, I think one day in my life I need to go supersonic, it must be one exhilarating experience, James may did it, why can't I?

10,000... you are more right than most know

Long live slide-rule engineering

?? I thought the blackbird flies about 2000 mph max......

A general rule of thumb... People who worked on the Blackbird, or the people who know those who did won't present what an SR is capable of unless it's already public domain.

According to my info, it was a little less than 6,000... average velocity from take off to destination. Still, I'd take that with a little grain of salt.

The world aircraft speed record still belongs to the X-15 with a speed of 4,519 mph at the altitude of 191,664 feet... I don't think that the Blackbird could top that with turbo reactors/ramjets that need minimum amount of air to function properly.

The last one also holds the 6,481 to 0 record.

AND YET, MOST PEOPLE BELIEVE THAT THE ONLY MODEL OF THE sr-71 WAS THE code named blackbird... forgetting about the TY-71, the D-2 drone (unmanned) the YF-13 (forward winged sr-71) which hold capabilities still classified, heck most people still think the TR-3A/B does not exist, I'm sure we have gone over mach 5 and possibly continue to do so every day

I am not doubting that we gone over Mach 5, but are they manned flights?

well. 6000 mph is tongue and cheek. Manned flight at or above Mach 5 has happened in the vehicle in question.

I liked the YF-70. It's ugly in a beautiful way.

Cessna has a hypersonic version of their C 162 but it's also classified...

Seriously do you know how much heat is generated at the tip of the wings at Mach 5? Don't forget that the melting point of Titanium is 3135°F (1725°C) and that at the difference to the Balckbird (and derived) the X-15 can fly in rarefied air environment (it's rocket propelled).

BTW never heard about your declination of the SR-71. I knew about the A-11, A-12, M-21, YF-12 and SR-71A-B-C.

This is what I found concerning the D-2
