The Chinese Co-Pilot was an aviator working for Lao Che Air Freight. In 1935, he served aboard a cargo-carrying Ford Tri-Motor Airplane. On one scheduled cargo flight scheduled to leave in the early morning one day in 1935, the plane got three last-minute passengers, booked by Earl Weber. The passengers arrived at Nang Tao Airport and quickly got aboard the plane, which the pilot was preparing for take-off. Once the passengers got aboard, the pilot and his co-pilot spied their employer, Lao Che smiling outside the airport gate. Salting their boss, the pilot took off.
The co-pilot had received word from Lao Che to ditch the plane, killing the passengers, Indiana Jones, Willie Scott, and Short Round. After refueling in Chungking, they flew west, towards India, instead of flying south toward the supposed destination, Bangkok. When they were over the eastern Siwalik range, the pilot told him that it was the time to make their move, as their passengers were asleep. The co-pilot dumped the plane's fuel supply. After the pilot had made his way to the back of the cabin, the co-pilot tiptoed past the sleeping passengers. After the pilot opened the rear door, causing the poultry feathers to fly about the cabin, the co-pilot had to be prodded to the door to parachute out.
The co-pilot was later questioned by René Emile Belloq over the certainty of Jones' death.
