@GGtharos:
have you ever flown an Eagle?
for sure not, otherwise you would not write such stupied thing.
first, mach 2.5 do you know how much airpressure exist up there?
my cousin was at 41000 feet over the atlantic.
his jet the 86-0159 is known in europe to have the best engines overseas which are available for the f-15c, and he only managed mach 2.3, point.
it is not possible to go faster then that without sevearly damaging the frame cause of heat and drag
there is no point to it to convince me from something other cause i do know
