The pilots of the two planes that crashed at Biggin Hill over the weekend were covered by insurance. All pilots have to prove they have third-party insurance before they are allowed to take part in the display.
The pilot of De Havilland Vampire, which came down in the last display of the day on Saturday, killing both men on board, was insured through broker HSBC.
The World War II Bell Kingcobra fighter which crashed on Sunday had insurance through Gallaghers.
It is up to the owners to insure the planes. An industry commentator said the Vampire was worth around £75,000 and the recently restored Kingcobra about £700,000.
