The prominent full-span leading-edge slats, high wing braced with struts, and squared-off wingtips are distinctive STOL features. Ground clearance on the wide-track undercarriage is generous to handle rough strips.

History

Developed from research by Professors Otto Koppen and Lynn Bollinger at MIT, the Courier was designed from the outset for extreme STOL performance. The prototype flew in 1949 and the H-391 entered production in 1953. The US military used the U-10 Courier in Vietnam for psychological operations and special forces support. Mission Aviation Fellowship and Wycliffe Bible Translators operated Couriers globally.

Variants

H-391, H-395, H-250, H-295, H-700 Courier series with varying engines from 260 to 350 hp. The military U-10A/B were lightly modified civil aircraft.

Where you'll see it

Widespread use in Africa, Latin America, Papua New Guinea, and Southeast Asia for missionary, medical, and utility bush flying; US special forces used it in Vietnam.
