Why Does the SR-71 Blackbird Leak Fuel

[KN-]

Missed the part where the designed to fuel so that when it leaked on the ground it couldn’t light on fire. There stories of the ground crews throwing burning cigarettes into the fuel for fun

It's actually the other way round. The SR71 was designed to leak fuel in flight. At the ground the metal shrunk and completely sealed the fuel tanks. Small amounts of fuel could gather on the surface and trip down shortly after touchdown. But it did normally not leak more than a few drops. Because you can't start the engines when there's gas on the ground. But you need to start the engines for many technical checks. Don't trust AI videos.

Still I think it’s bad solution. How all rockets on liquid fuel don’t leak like Black Bird? Space rockets and ICBM. They can keep fuel for long time. I bet they get much faster speed and much higher temperature. I think those guys who accepted those fuel tanks or slow or took a bribe

Why didn't they use rubber bladders for the fuel? Sounds stupid and false to me.
