From 2004 until 2021, the company was developing a 10-passenger supersonic jet to cut transatlantic flights by three hours, using "boomless cruise" technology to negate the sonic boom.[3][4] It was expected to be the first supersonic aircraft without an afterburner to lower emissions, and the first to run on biofuels.[5][6]
Aerion abruptly announced on May 21, 2021, that the company would be shutting down due to inability to raise needed capital to proceed.[7]
