New Supersonic Aircraft By Leap Aerospace Another supersonic contender has leaped into the limelight. This time it's a supersonic jet from a company called Leap Aerospace with very ambitious plans and a slightly different approach. We have seen that trying to develop and certify a supersonic aircraft as a startup is a very daunting task with a few players, notably two in the last years being the stand-out contenders. Those are Aerion and BOOM but the former realized just how expensive the endeavor is. Aerion folded unexpected earlier this year leaving BOOM to be the remaining viable developer of a supersonic aircraft intended for the business jet/commercial sector. In fact their latest success was from a substantial United Airlines order.
