Overture: The world's
fastest airliner

Mach 1.7. Half the travel time. Fares similar to today's business class.

Overture will fly passengers between global destinations in half the time of today's aircraft, with orders and pre-orders from United, American and Japan Airlines.

What is supersonic flight?

Supersonic flight means flying faster than the speed of sound, about 660 mph at 60,000 ft. Overture cruises at Mach 1.7, around 1,100 mph and twice the speed of today’s airliners.

The fastest passenger flight, 1919 to today

Why are we flying at the same speed as in 1958?

In 1976 you could cross the Atlantic at twice the speed of sound. Since Concorde retired in 2003, the fastest flight you can book is no faster than one in the 1960s.

  1. 1919: Early airliners, Mach 0.13. The Atlantic by ocean liner: about 4–5 days.
  2. 1936: Douglas DC-3, Mach 0.28. The Atlantic by ocean liner: about 4–5 days.
  3. 1946: Lockheed Constellation, Mach 0.44. New York → London in about 15½h, two refuelling stops.
  4. 1952: de Havilland Comet, Mach 0.7. The first jet airliner; the Atlantic still by propeller.
  5. 1954: Propeller airliners, Mach 0.47. The Comet grounded: back to propellers.
  6. 1958: Comet 4 and Boeing 707, Mach 0.82. New York → London in about 7h.
  7. 1976: Concorde, Mach 2.02. London → Washington in under 4 hours.
  8. 1977: Concorde, Mach 2.02. New York → London in about 3h 30m.
  9. 2003: Subsonic jets, Mach 0.85. New York → London in about 7h, again.
  10. Next: Overture, Mach 1.7. New York → London in about 3h 30m.

Symphony: an engine built for supersonic flight

A shared core for power and flight

No off-the-shelf engine could do this, so Boom is building its own. Symphony shares its core with Superpower, Boom’s natural gas turbine. Once Superpower enters service, its operating experience and reliability data will help inform Symphony’s development.
