Supersonic Passenger Flight
NASA's X-59 aircraft rekindles hopes for commercial supersonic air travel
The X-59, which is smaller and slower than Concorde, has a maximum speed of around 1,500 kph and is estimated to cut travel time from New York to London by about 3 hours and 30 minutes

Aviation startup Boom Technology picks engine designer for supersonic plane
Aviation startup Boom Technology says it will power supersonic passenger jets with engines designed by a company better known for making small engines used on drones and cruise missiles. Boom said Tuesday that Florida Turbine Technologies, or FTT, will design the engines with help from GE Additive, a division of General Electric. Boom says the plane could be making test flights in 2026 and carrying passengers a few years after that. The company says its 88-seat jet, called Overture, will use four engines, fly up to 1.7 times the speed of sound about 1,300 mph and use sustainable aviation fuel. The Denver company generates plenty of scepticism in aviation circles for its ambitious schedule and certitude that supersonic passenger flights can be economically feasible and environmentally benign Concorde wasn't, so it stopped flying. Getting the plane certified will be daunting, with regulators more cautious after two deadly Boeing Max crashes. Flights would likely be limited to oc
