Are you Grandson of 'Watty' Watkinson 66sqn
66sqn led by 'Dizzie' Allen I think
Flew Spitfires and crashed one in a tree in Sept 1940 just along the road here in East Sussex?
Could you possibly kindly check your Grandfathers log book for 27/28th Sept 1940
There is some mystery surrounding the circumstances in which he got this aicraft down, which a local farmer here says was resting in the tree tops
The suggestion is that if he bailed out on this date that his Spitfire somehow landed in the canopy of Newbridge Wood which is close to where I live in Tunbridge Wells
