Come on people, this was not a "dangerous stunt" They just flew down the runway. If just flying an aircraft in basically a straight and level configuration, is an air show, many of us need some serious raises.
To me the only question is, did he have permission or not from the controlling agency and or the brass from the company. Judging by the initial reaction from the company I would say that was not the issue. At least until all the crying about the "stunt" started.
