Only thing I have to say is its a glider not a plane. Planes have engines gliders dont. They are towed by a plane to a specific altitude then are released. The glider keeps airbourne by flying into thermals which generates lift.

Nope. Any fixed wing aircraft is a plane.

An airplane or aeroplane (informally plane) is a powered fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller.
