Hermeus(@hermeuscorp):New top speed unlocked: Mach 1.6. Since supersonic, the team hasn’t stopped pushing to expand the envelope to higher speeds. Last week, Quarterhorse Mk 2.1 broke its own record — reaching Mach 1.6 on just its fourth flight, with under 90 minutes of total flight time logged. The fastest way to build fast aircraft is to keep flying them.
