On another forum, several posters who were at Duxford July 10 were insisting that the Skyraider pilot sat in his cockpit for 15 minutes before climbing out... without anyone going to the aircraft in that time.
Another poster checked his camera, and it was 4 minutes 30 seconds between the pic of the Skyraider taxying to a stop and the pic of the pilot walking around the aircraft inspecting the damage.
Those other eye-witnesses had tripled the actual time of the events... not uncommon in such circumstances.
