Re: Military Flight Safety

Seems like IAF is pinning its hopes on the C-295 as replacement to the An-32's, the weather isn't going to be different, does the C-295 have more power margin? if so, can it perform assault landings, perhaps suitable for landing on airstrips in the bowls of the mountains?

One of the A4 tests, it is said to have reached 800km altitude, just to reinforce the message to the north west neighbor they should make the ASAT reach an electronic target at higher altitude while intersecting the orbit of one of their sat a few hours ahead of the sat passing that point over India.
