Other mistake: When Quin is cutting the plane that's stuck in a tree, he uses a saw, that looks brand new. He's just been chased by pirates and jumped off a cliff - where did he get the saw from? Anything in the plane would be rusty by this point.
Other mistake: Watch Harrison Ford's hair throughout the film. When they are making the rafts out of the plane, you can see that he has had his hair cut. I never knew that they had a barber's on that island.
Answer: Quin would likely have tools stored in his own airplane.
