[Peter Cornwell]

alanatabz, The correct unit of this loss is 1./ KüFlGr. 906 & the date as follows:

16 September 1940 1./ KüFlGr. 906 Heinkel He115C-1 (2754). Crew lost their bearings in deteriorating weather conditions during night armed-reconnaissance sortie over Kinnairds Head and flew into the ground near Aberdour 10.00 p.m. FF Hptmn Heinrich Kothe (Staffelkapitän) and BF Uffz Herbert Meissner both captured unhurt, BO Lt zur See Hans-Otto Aldus captured injured. Aircraft 8L+GH 100% write-off.

As has already been said, they took off from the German island of Norderney or 'Ney' for short.

RT, The only losses to Seenotflugkdo.3 that I have listed around this time are:

15 September 1940 Seenotflugkdo 3 Heinkel He 59 (1513). Crashed during heavy landing in the Channel off Dungeness during air-sea rescue mission 1.30 p.m. FF Uffz [ ] Bauer and rest of crew all rescued unhurt by German vessel Seelöwe. Aircraft TW+HO 100% write-off.

17 September 1940 Seenotflugkdo. 3 Heinkel He59D (1848). Damaged in collision with U-boat during storm while moored in Boulogne harbour. No personnel casualties. Aircraft NE+TA 30% damaged but repairable.

Nothing on 16 September 1940 nor anything off the south coast of Ireland I'm afraid.
