not O.K. Definitely suffering from shock, and probably suffering from pelvic or vertebrae fractures as well, and it's more than likely going to be a long period of convalescence for him.
The high level of downward G-forces in the crash landing is clearly indicated by the downwards fracturing of both wings.
