looks like Rainbow is pulling a Faults Stall.





that's where a stunt airplane points its nose straight up, climbing as high as it can, until either gravity or the lack of speed drags it tail first back down... the pilot then lays the plane on its back and inters freefall...





it's a dangerous stunt do to the fact the plain's engine can stall out, or the pilot can black-out while trying to recover and crash.
