Miles Aerovan
Hi, yes it was opposite the Romper we used to watch them, my sister in law has a photo of one on the concrete, my Brother who is 11 years older than me has confirmed the aircraft was the Aerovan.
A Havarde trainer also crashed at the same spot in 1950 my brother remembers this one,i also spent most of my time near Fairey watching the now classics,a friend of mine ran onto the tarmac and picked up a spent starter cartidge from a Gannet, a mechanic tried to catch him.
Happy Days
