The first Solar Impulse 2 maintenance flight took place on Friday 26 of February. The plane took off from Kalaeloa airport at 4:32PM UTC with test pilot Markus Scherdel in the cockpit, and landed at 6:05PM UTC. During the hour and a half that it lasted, the team based at the Mission Control Center performed maintenance checks to verify that the technology installed in the aircraft ran smoothly, such as the stabilisation and cooling system, which both performed superbly. Si2 flew up to 8,000 feet over the Pacific Ocean and then returned to the Kalaeloa base.
