Has a 747 ever gone supersonic?
Has a 747 ever gone supersonic? Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747-100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.
Is it illegal to go Mach 1?
Currently, U.S. law prohibits flight in excess of Mach 1 over land unless specifically authorized by the FAA for purposes stated in the regulations. The two supersonic rulemaking activities would not rescind the prohibition of flight in excess of Mach 1 over land.
Why is sonic boom banned?
Supersonic flight is banned over land in the US without special government authorization because of the inconvenient noises and tremors it can produce.
What is the 1100 mph plane?
Spike Aerospace, founded in 2013 Max Kachoria of NASA, built an 18-passenger supersonic jet with low-sonic boom, fuel efficiency, speeds up to 1,100 mph, and flight times slashed in half. Their current model is the S-512 which can get passengers to cities in a moment's notice: NYC to London: 3 hours.
Can a commercial plane reach Mach 1?
The transonic regime 80, though no commercial aircraft in operation today exceeds Mach 1. Instead, they can achieve transonic speeds, including the Boeing 747–8I (cruising speed of Mach 0.86) and Airbus 380 (cruising speed of Mach 0.85).
Has an airliner ever broke the sound barrier?
Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.
Why is it illegal to go supersonic?
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
Will we ever fly supersonic again?
In any case, supersonic air travel for the masses looks like it's genuinely back on the cards. Boom is aiming for the first Overture test flights to take off in 2026 and for the planes to go into public service by 2029.
What is the fastest a 747 has ever flown?
Aided by a more powerful jet stream than usual, this rapid journey saw the 747 reach a top speed of 825 mph. Photo: Markus Mainka I Shutterstock. Popular Mechanics reports that the reason for it being so powerful on this occasion was a 'bomb cyclone' near Greenland.
