Concorde, which debuted at the Paris Air Show 48 years ago this week, had a top speed of Mach 2.

The full plane comes with two configurations of either 55 business class seats or 15 business with 30 first class seats or longer flights. The plane would have a list price to customers of $200 million.

A business class ticket from London to New York is estimated at $5,000.

The company wants the plane in the skies by 2023 but is first developing a smaller supersonic jet to test the technology.

Scholl said the XB-1 Supersonic Demonstrator will fly in Denver late next year after passing a major performance and safety test.

“We now have everything required to build history’s first independently developed supersonic aircraft—the funding, technical design, and manufacturing partners,” said Scholl.

GE, Honeywell, Tencate and Stratasys are among the firms working on the Boom Supersonic development.
