In 1981, I was young Airman charged with loading “ALCM missiles” on B-52’s in upstate NY.
When you attempt to traverse the aircraft from the cockpit to its tail, there was hardly the ability to stand up.
The entire interior fuselage was packed with so much equipment that making the journey could take 30 minutes of crawling on your knees.
That was in 1981. I suspect that most of that interior space has been freed up for other purposes since then.
Personally, I was a fan of the F-15. When it was introduced, it was the only aircraft that could accelerate while going vertical.
And the SR-71 is an insane feet of engineering.
Can you imagine the conservation between the Generals and the Lockheed team when the SR-71 was first introduced ?
Generals;
“What is leaking from the plane?”
Lockheed;
“That’s fuel, sir”
General;
“I hope that is something you can correct”
Lockheed;
“No Sir, that is by design”
Kinda like motor oil in a Harley, the leak is a good sign. So long as it's leaking you know there still some in there.
