Monday was a great milestone for the team. We performed five tests from 25 to 60 mph with two different pilots. All objectives were achieved. They were: condition the brakes and evaluate the landing gear/brake steering/skid shoe performance and general ground handling. The vehicle performed as expected and we're excited to move into the manned phase of the test program.
