Remember the experiments the French carried out at Marseilles in 19647 "Was that the "Jericho Trumpet?"'

Characteristic Ju 87 Stuka was inverted gull wings (broken wings) and sirens called Jericho Trumpet.

The aircraft was easily recognisable by its inverted gull wings, fixed spatted undercarriage and its infamous Jericho-Trompete ("Jericho Trumpet") wailing siren, becoming the propaganda symbol of German air power and the blitzkrieg victories of 1939-1942.
