Basic engineering on a SR71
Leaks fuel like a colendar while on the ground as the tanks need airframe kinetic expansion of mach 2 to seal.The type of Avtur used was unique to the aircraft as well.
Hydraulic and engine oil has to be replenished just before start up and removed after shut down because it reverts to a waxy / solid state at room temperature.
A No Brainer....
"Or how about a Valiant - the only V bomber that ever actually dropped a nuke?"
Cos the only one in existance is the one that dropped the first British Nuke.
A Building has been build around it (Cosfords Cold War Museum). If there were any other airframes , they will not have been maintained for 40 years and the rear spars would have to be redesigned and rebuilt due to their tendancy to unzip...
