Supersonic jetliner travel, which ended more than a decade ago with the Concorde, is set for a boost after Japan Airlines Co. agreed to invest $10 million (about ¥1.1 billion) in Colorado startup Boom Technology Inc. The deal will give JAL a 1 percent stake in the Denver-based company.

The airline also secured an option to purchase as many as 20 of the aircraft Boom is developing, the two companies said in a statement Tuesday. JAL is the second company to announce an intention to purchase Boom's supersonic jet, after billionaire Richard Branson's Virgin Atlantic.

Boom is planning to build a 45-to-55 seat aircraft that cruises at Mach 2.2 (1,451 miles per hour) — capable of whisking passengers between Tokyo and San Francisco in 5½ hours. The Concorde, flown by British Airways and Air France, retired in 2003 after almost three decades in service as customers abandoned the jets amid hefty operating costs.
