You honkies need to realize high altitude operation is a very diff. thing when you get up there. The air density requires totally, vastly different things than it does down low. Shit like the SR71 is meant for flight up there, and it’s not maneuverable at all.
(Granted I’ve not researched this and it’s all off the top of my head from experience over the years and assorted brochure reading, give a lot of slack on numbers and such)
When you take a plane up to its service ceiling, it’s a bit like trying to run on black ice. You don’t have the ability to pivot and juke like you would on tarmac. It’s that same sensation when you’re at the absolute limit, ass below the horizon as the plane grunts and pulls at just to maintain a 2 fpm climb. You’re just barely getting the required lift to maintain your altitude, or you’re climbing just enough to outpace your rate of descent. You’re on the edge of a stall, you can feel it, you’re asking for too much from your wings, and the plane wallows like a fat old man after thanksgiving as he waddles to the niggerball couch.
