I was pushing aircraft to park at hangar. Once chocked was going to pull the push tractor back and in to set it up for a crewmate to pull the pin out. As I thought I had my foot on the brake had it on the accelerator; the tractor lunged backwards and pulled the front nose strut out and the aircraft collapsed. Nobody was injured and all were safe.
A Maintenance Technician reported a nose landing gear collapse when the tug was unintentionally accelerated in reverse.
