I think that sounds reasonable.
I really wanted to know if submarines can detect that they've been spotted on radar. It is commonplace on planes; do subs have that equipment? Visual detection of an ASW aircraft or being pinged are of course warning signals.
I don't think that was a reasonable answer, and I don't think that would be a reasonable action.
The Atlantique was shot down in Indian airspace. It was not the first incident of an unarmed plane in violation of airspace being shot down, and it was, all said and done, in military markings.
In 65, a civilian aircraft, carrying the then Gujarat Chief Minister and his entourage, was shot down in Indian airspace. Admittedly it was during hostilities, but the pilot tried to signal the Pakistani pilot by waggling his wings. However, under instructions from ground control, the Pakistani pilot attacked and brought the plane down.
Please do not quote examples that have no bearing on the present situation. Even now, aircraft violating the other country's air space are warned, not shot down. This bloodthirsty approach of yours is quite barbaric.
No; they would be identical.
