Very interesting case (remember to turn on English subtitles, the podcast is in Polish). In 1939 Polish clerk who fled from attacking nazis to Bolimowska Forest near Warsaw witnessed a strange occurence. Nine German bombers were literally burnt in the air. Later local villagers said that "fast plane" passed over nazi squadron and burnt it.

The witness wrote a letter to one of Polish newspapers in 1959.
