Corrected entry: When Charlie, Grandpa Joe, and Wonka are in the wonkavator, Wonka looks at something that says altometer, and states "If we don't gain enough speed, we'll never make it through." Altitude however is the distance you are from the ground when in the air, not the speed that you are going.

Correction: He's worried that they won't gain enough speed by the time they reach the altitude of the roof. Therefore, he is looking at the altimeter to see how close to the roof they are.
