Halcyon is a passenger aircraft capable of accelerating 125+ trans-oceanic routes at hypersonic speeds – five times faster than any commercial aircraft today. 

More than 500,000 business class passengers travel from New York to London each year. Flying at Mach 5 would save them six hours on a one-way trip. That’s three million hours saved per year – on just one route, in just one year.

Historically, accelerating transportation networks has resulted in massive social and economic growth. Hypersonic travel has the potential to add more than $4 trillion of global GDP growth per year by radically accelerating the speed of commerce and cultural exchange.
