Widger:
It is also worth saying that whilst Shoreham was the first fatality of uninvolved third parties, you could say the UK has been very lucky in the last 63 years. Shoreham was not the only accident in the last few years.
The Biggin Hill A-26 comes to mind: "21 September 1980 a Douglas B-26 Invader (registered N3710G) crashed during an air display. The aircraft was attempting to carry out a climbing roll in front of the crowd when the nose dropped sharply, and the aircraft continued rolling until it dropped vertically into a valley. The pilot and six passengers were killed." It barely missed a group of spectators and a row of houses, and one of the passengers was a child. So it could have been a lot worse.
