Comment: Commercial airliners CANNOT

(See in situ)


Commercial airliners CANNOT

Commercial airliners CANNOT fly supersonic. When a plane hits supersonic it creates a "sonic boom". What that sonic boom is is air travels AWAY from the airplane. Aircraft that travel supersonic are designed do compensate for such. A commercial airliner is not.

When a commercial airliner reaches supersonic and creates the boom, air travels away from the engine inlet, the engine suffers a compressor stall then flames out. Dead engine. When the air reverses over the wing it looses lift, and the flight control surfaces loose functionality due to the lack of air flow across them. The plane simply won't fly supersonic, and that is even without consideration of structural stress on a plane not designed for such...

Most likely the aircraft was traveling 510 MPH, not 510 knots. 510 MPH is a speed within the capability of a commercial airliner. 661knots (761 MPH at sea level) is supersonic at sea level. The 767 is designed for a max speed of Mach 0.8, or 533 MPH at sea level. 510 MPH would be consistent with such. To have exceeded 533 MPH at sea level would have required a steep dive, the engines would not provided the thrust required to exceed this speed at such a low altitude in level flight.
