Centaurus
regarding the C-119 incident many years ago a friend was doing his glider tow rating in a Piper Cub with the instructor seated in the back seat during the climb out around 200ft the instructor yelled out (no intercom) "Relax" he thought she said "Release" so he pulled the tow release the experienced glider pilot was able to complete a successful return to land with the tow line still attached to his glider.
