Construction and operation

The Pushpak was a high-wing braced monoplane with a fixed tailwheel landing gear.[1] The fuselage was built from metal tubing, the wing aluminum ribs on a wooden spar, all covered in fabric.[1] The Pushpak first flew on 28 September 1958 and was powered by a 90 hp (67 kW) Continental flat-four engine.[1]

Around 160 aircraft were produced for Indian flying clubs for use as basic trainers.[1] Two examples were gifted to Malaysia and were later sold to private pilot owners in the United Kingdom. These examples remained in active operation in 2013.[2]

gollark: I mean, if Thue makes your development experience nicer, go for it!
gollark: R U S T!
gollark: Use Rust. Rust is good. All Hail Rust.
gollark: Then still probably not, given how often your stuff gets used...
gollark: Let's be honest, 90% of the time you won't go anywhere near amounts of data which will cause performance problems in esolangs.
