After a number of previous successful test flights, Blue Jay 3 careened out of control with 1.75kg of payload, its wing snapped mid-flight, and it crashed into the ground at relatively high speed, splintering and cracking the fuselage. Fortunately, it didn’t hit anything or anyone on the way down, and Blue Jay 4 is still in one piece. The exact cause is unknown, but it appears to have been loss of aileron control after the wing warped, sending the plane into a sharp left turn. The force broke the left half of the wing off where it was attached to the fuselage.
