Strange Airplane Cuts Antics Over Davenport Today

Democrat and Leader de Davenport (Iowa),
s1Clark, J. E.: "mystery airplane, Iowa, 1928", Magonia Exchange, 2007-12-13

A large airplane with engines roaring wide open attracted much attention this morning as it cut all kinds of capers at a low altitude over Davenport. Tho [sic] the plane did not stop at either airport in the Tri-Cities[,] men at the Davenport field identified it as one having a 12-cylinder Liberty motor.

The pilot's favorite trick and one that caused the loud roar of the motor was to climb at a sharp angle and then turn his plane almost directly to the ground tearing earthward at a tremendous speed.
