[Alex Smart]

Hello,
This subject I am sure has been delt with on this forum before, but I just canot find it.
So here goes again.

30-08-39.....74 Sqn.....K9861.....stalled to avoid collision.....sgt. Cyril Douglas Gower.....killed.
02-09-39.....611 Sqn.....K9985.....flew into ground.....P/O. Leech.....killed.
04-09-39..... ? .....K5054.....stalled.....F/Lt. White.....killed.
06-09-39.....66 Sqn.....K9986.....crashed at night.....P/O. DGB Patton.....killed.

30-12-39.....602 Sqn.....K9977.....lost wing, E Lothian.....Sgt. BP Bailey.....killed.

My questions are -
1. What were Sgt. Mitchell's initials ?
2. What were P/O. Leech's initials ?
3. To which Squadron was K5054 attached on 4th March 39 ?
4. What were F/Lt. White's initials ?
5. Confirmation of K9986's pilot being P/O Patton ?

I can find no details in CWGC site re Leech,White or Patton why would this be ?

Many thanks
Alex
