The first was when the camera was used by the navy aboard HMS Reclaim to recover the wreckage of a Comet 1 jet aircraft which crashed off Elba. The successful recovery of the Comet wreckage led to the ground breaking discovery of the phenomenon called Metal Fatigue.

Experiments were carried out using a camera fitted into a helicopter at Pye. The aim was to see how well the system operated when surveying activity on the ground. The aircraft was a Bristol Sycamore and the radio link was at 250MHz.
