The company says its 40-seater aircrafts, at their cruising altitude of 60,000 feet, will reduce the time to fly from New York to London by half. So for a roundtrip price of $5,000, the travelers will be able to cover this distance in only 3.4 hours. Boom founder Blake Scholl said, “Imagine departing from New York at 6 a.m., and landing at Heathrow by 2:30 p.m. London time… You’ll be able to make afternoon meetings, you can stay until 9:30 p.m., have a full productive day, and and back in New York at 8 p.m. [local time] so you can tuck your kids into bed.”
