sycamore,
I don't doubt the veracity of any statements here, merely pointing out that the MARHAM bloodhounds went in May 1964, those at West Raynham, which FED may well have been referring to, indeed came and went much later.
They were at Marham, I started flying Valiants in 1962 and even though I was based at Honington practice diversions to Marham, a Master Diversion, were quite frequent.
Whenever I was opn finals at Marham I was watching the runway!
My aircraft never deviated from the glide path and centreline. They wouldn't dare!
