Never did hear of the flight of a RAAF Canberra through a Townsville hangar. The hangar looks like the big old one at Darwin.
PhotoShop could readily combine two or more photos. The big mistake in the shot is the airman on the floor. He would not have known of the approach of the aircraft in time to go prostrate.
The forward view from that terrible Canberra canopy would be a huge deterrant to such a blatant act even though I had much subdued asperations to loop a Canberra around the Sydney Harbour Bridge. The visual target of the open mouth of a hangar seems incredibly small until one is very close and this would be enough to deter anyone in an aircraft at speed unless both occupants were prepared for inevitable nasty consequences. Unknowns would be obstructions hanging down from the hangar roof and what clearance to allow for the fin.
There seems to be something wrong with the top of the nacelle of the right engine.
