Den 11. september 1944 styrtede LAN LM511 i Smålandsfarvandet nordøst for Vejrø omkring her. Flyvehistorisk Tidsskrift skriver:
"11.-12. september 1944 (kl. 23:05) Smålandsfarvandet NØ for Vejrø. Lancaster B. III, LM511, (GI-C)
622 BS, 3 BG, Mildenhall, Suffolk (Minering: Østersøen nær Rostock) 7 MIA.

Medens 240 RAF bombefly fløj til Darmstadt, fløj 76 Halifaxes og Lancasters til Kattegat og den vestlige del af Østersøen. Tre af mineflyene blev skudt
ned af tyske natjagere. Kl. 23:05 blev en kort luftkamp observeret nordøst for Vejrø. Umiddelbart efter skete en voldsom eksplosion, og større mængder brændende
benzin blev observeret lang tid efter.

Da nedstyrtningsstedet for de to øvrige minefly er kendt, kan der kun være tale om LM511.
Efter krigen er en del vraggods fundet i området, men der er aldrig fundet spor efter de omkomne besætningsmedlemmer." (FT 86-92-31) 7 flyvere.

22 APR 2020 sendte Brian Thomsen oplysninger fra Karen Petersen, Fejø, der så både det store bombefly og den mindre tyske natjager, se Karen Fejø.

"11 - 12 September 1944 (23:05) The Smålandsfarvandet NE of  Vejrø. Lancaster B. III, LM511, (GI-C)
622 BS, 3 BG, Mildenhall, Suffolk (Minelaying: The Baltic Sea near Rostock) 7 MIA.

While 240 bombers from the RAF raided Darmstadt, 76 Halifaxes and Lancasters flew to the Kattegat and the western part of the Baltic Sea.
3 of the minelaying planes were shot down by German night fighters. At 23:05 a short aerial combat was observed north east of Vejrø.
Right after that there was a tremendous explosion, and a lot of burning fuel was seen for a long time. As the crash sites of the 2 other minelaying planes are known,
this can only be LM511. Pieces of wreckage were found in the area after the war, but no trace of the perished crew members has ever been found." (FT 86-92-31)

Karen Fejø (see map) saw a big burning plane and a small plane that came from the south east, marked with red. Matches the Lancaster attacked by a night fighter.
