Life/death situation! please answer-really easy?

I would use the foil wrapper from the chewing gum and the lenses from my glasses to focus a beam of sunlight on a fixed point so that it would heat up, and eventually start on fire. The fire alarms would go off, and the kidnappers would be forced to land the plane. When they came back to see where the fire was, I would scatter mints all over the floor so they would trip and fall. Then I would exit the plane and make my escape.
