Masten flight with engine restart

“We’re extremely excited and very proud to announce that we now have in-air re-light capability,” said David Masten, CEO. “The ability to turn off our engine, re-ignite it in flight, successfully regain control and land was the next big milestone as we expand our flight envelope to include high altitude flights. Each milestone we hit makes the path to space much clearer.”

These teams are creating some incredible rockets, which will prove useful as landers in the future.
