The American company Boom Supersonic is developing the Overture airliner, designed to cruise at Mach 1.7 and carry 60-80 passengers. The aircraft will operate entirely on Sustainable Aviation Fuel (SAF).

Its demonstrator, XB-1, completed supersonic flight tests in early 2025, validating Overture's design. Rollout is targeted for 2027, with commercial service planned by 2029 and orders already placed by United Airlines and American Airlines.

This development follows the historical context of the Boeing 2707 Supersonic Transport project, which was canceled in 1971 due to environmental concerns and economic challenges. The 2707 mock-up now resides at the Museum of Flight in Washington, alongside a British Airways Concorde, illustrating the legacy of supersonic travel.
