Trust me, that would be the end of India if they did something like that to Pakistan!
Din't some thing like this happen back in 1997.
We din't have a war ...did we now?
Last May (1997), an Indian Force (IAF) Mikoyan MiG-25RB Foxbat-B reconnaissance aircraft created a furore when the pilot flew faster than Mach 2 over Pakistani territory following a reconnaissance mission into Pakistan airspace. The Foxbat broke the sound barrier while flying at an altitude of around 65,000 feet, otherwise the mission would have remained covert, at least to the general public. The Pakistan Government considered the breaking of the sound barrier as deliberate: to make the point that the Pakistan Air Force (PAF) has no aircraft in its inventory which can come close to the cruising height of the MiG-25 (up to 74,000 feet).
