Militär-Apparat MA-7
Type of aircraft
The Militär-Apparat MA-7, also known as the Häfeli MA-7 and K & W MA-7, was a prototype fighter designed by August Häfeli in Switzerland. It flew in two different engine configurations, neither of which were deemed satisfactory and so the type did not enter series production. However, it did achieve a Swiss record for flying at an altitude of 9,800 metres (32,200 feet) above sea level in 1926.
