Stralsund 'air ships'
Fishermen in Swedish Pomerania reported ships fighting in the sky over the Baltic, and then a plate-shaped object over St Nicholas Church.
1665 CE · 54.31, 13.09 · status: account
The account
Contemporary accounts from 1665 describe flocks of birds that became battling ships, then a dark grey, hat-shaped disc. Witnesses were said to fall ill afterwards. The event was taken as an omen from God.
The sceptical view
Proposed explanations include cloud formations, mirages over the sea (fata morgana) and a rare halo display.
