The second of these achieved stable transition to supersonic flight.

Early examples provided a solution to the problem of supersonic flight when engine power was limited.

But others experts with an eye on business travel across the Pacific say there will be a market for supersonic commercial flights.

The weapon's supersonic flight was an exercise in extreme delicacy.

The group offering the $10 million said this was the first supersonic flight in pursuit of the prize.

"Anyone who says it's the end for supersonic flights has got it wrong," he told the daily Liberation.

This seemingly simple innovation was one of the key technologies that made supersonic flight possible.

Capable of supersonic flight the project was cancelled in July 1957 after only 12 examples had been built.

That research led to the first supersonic flight and could help solve the woes you so rightly describe.

Forty-seven low-level supersonic flights took place over a period of two months.
