Hey i just heard on the news that two blasts heard in Rawalpindi were cause due to PAF. Any ideas who broke the sound barrier?

Yeah PAFs F-7P fighter broke the sound barrier when it dived from 40,000 to 15,000 feet. The locals thought that a bomb has blown some where but it was actually the sonic boomb.

It is reported in AHQ that the fighter was on scheduled Functional Control Flight Mission when this happened.

RAWALPINDI: An F-7P fighter aircraft of Pakistan Air Force crossed the sound barrier Monday, causing a big boom, which was heard in the twin cities and other areas, according to a PAF statement issued here.

The aircraft was on a scheduled Functional Control Flight Mission when it crossed the sound barrier in Pindigheb area. At the time the aircraft was in a process of transition from 40,000 feet altitude to 15,000 feet.

The fighter aircraft flew the planned maintenance check mission after overhaul at the Pakistan Aeronautical Complex, Kamra. The sonic boom waves traveled to adjacent areas due to high altitude and clear weather conditions.

According to experts military aircraft routinely accelerate to speeds greater than the sound speed, which is known as breaking the sound barrier.

Thank God no blast this time.

yeah but doing these things are legal?

I dont think testing aircraft up in the air involves any sort of legal controvercy especially if the aircraft is above 10000 feet.

10,000 feet is the minimum height for a supersonic fighter to cruise upon. And that F-7 was flying above 15000 feet.
