FV - the Lightning accident was well publicised at the time and was also captured on film.
2 Lightnings were tasked to position for a display which was due to take place the next day. The leader of the pair received an unofficial request to do a flypast at a nearby recruiting show - and aksed for approval. His authoriser refused this in no uncertain terms and ordered him to proceed directly to the airport as tasked. Later on the No 2 was still being prepped, so the leader was re-authorised to proceed on his own..... He flew past the recruiting display at 100-200 ft before flying an impromptu display which terminated when the ac stalled and crashed into the sea, killing the pilot.
Why on earth did he decide to do this? Who knows. Because it would almost certainly have been his last ever flight in the RAF had he landed at his destination in any case - such gross indiscipline would never have been excused.
