NASA mysteriously trying to pull world’s fastest plane, SR-71 Blackbird, out of retirement — and won’t say why
Seeing Blackbird fly again after all these years would be incredible. I’d love to know what NASA has planned for it.

They want a jet that works. It’s not NASA’s SR-71, the SR-71 was made by Lockheed.
F35s are chronically grounded with software issues. They want a plane that works.

The F-35 isn’t grounded, nor does it have anything to do with NASA.

Nor would an SR-71 play anywhere near the same role as an F-35 lol. They’re apples to oranges.
Replying to @Earthwormjim91@lemmy.world
they are both hypersonic aircraft.
Replying to @SaveTheTuaHawk@lemmy.ca
They are not. The F-35 has a top speed of Mach 1.6. It’s a supersonic aircraft.
The SR-71 has a top speed of Mach 3.2 lol. Literally twice as fast as the F-35 but still well short of the Mach 5 required for hypersonic flight.
The F-35 also has a flight ceiling of 50,000 feet, while the SR-71 has an 85,000 foot ceiling.
The SR-71 served exactly one role: High supersonic aerial reconnaissance. No weapons, nothing. Just fly higher and faster than anything else on the planet.
The F-35 is a strike fighter and air superiority fighter.
They’re really not comparable.

Technically, they’re both supersonic, not hypersonic, but yeah, that’s just semantics. The actual important detail is that the SR-71 is twice as fast (or more) as the F-35. There’s a lot of testing you can do with the former that’s just not possible with the latter.
