Today in aviation history – 30th July

On 30th July 1918 died Austro-Hungarian fighting pilot Frank Linke-Crawdford. He gained 27 aerial victories what put him on 4th place among other Austro-Hungarian fighting aces. On one of his aircrafts Linke-Crawford painted red and white chessboard. The sign was copied by Stefan Stec, and became a sign of Polish aviation (since 1993 white and red chessboard).
