Aircraft can leak oil, I vividly remember the US aggressor F-18s leaking oil on the ramp like drunkards. Some say that was not oil but water instead, also possible.
Regardless, it's an active duty aircraft of the air force without known issues. Tejas is many things, but it doesn't just lock up and crash. This looks like a very clear case of pilot error to me.
APU exhaust should be up top. Smoke generators are on the wing pylons as fake missiles. Interesting.
Yup pretty much open shut case of severe pilot error at low altitude if you ask me.
It bears uncanny resemblance to the Polish F-16 crash at an airshow rehearsal a couple months ago. Again what looks to be major pilot misjudgement in that one.
Sad.
Shoreham aircrash also comes to mind, that was again a loop with too little altitude for the thrust the old warbird (Hawker Hunter) was capable of. What was wild was the (blacked out) pilot survived the impact (being thrown out of canopy during impact) and was prosecuted for manslaughter of the casualties on the ground. I think he was acquitted.
But really pilots, however well trained they are, shouldnt let rush of blood get too much....its not worth it.
