Diego takes off into a substantial 25 mph windshear that begins at about 40 feet. His AirCreation Racer trike quickly pitches up so much that Diego had to quickly reduce power with the control bar pulled all the way back to his chest. Diego tried to land at two other inland airfields, but the turbulance was so extreme that it knocked his feet off of the controlpedals several times. He finally flew west to the ocean and landed on the beach where the wind, blowing in across the ocean was strong, but smooth. After landing at sundown, he had to remain seated in the trike, controlling the wing to keep the trike from being blown over. He made a cellphone call to us, and we arrived at the beach about 40 minutes later and disassembled the wing on the trike, in the dark while Diego remained seated, still controlling the wing.
