Liffy 1M, the aircraft in the film 'Silent Enemy' was likely WX547/51-15958.
This aircraft had suffered an undercarriage collapse on landing at Hal Far, Malta, on 13 Jan 56 and was subsequently written off. On 30 May 57, the remains were sold to Remus Films and pushed into the sea from cliffs at Hal Far.
Many thanks for that,
Lauriebe. So parts of that movie must have been made in Malta as well.
