Two blind pilots enter a plane. They have sunglasses and white sticks. As the plane starts to move, the passengers are uncomfortable. The plane gains speed, but it stays on the ground. The remaining runway gets smaller and smaller, and the plane is rushing towards a fence.
The passengers start shrieking and suddenly the plane lifts, avoiding the fence at the last second. All the passengers calm down, thinking it was a bad joke.
In the pilot cabin, the co-pilot turns to the pilot and says : “You know what? One day they’re going to scream too late, and we’re all going to die”
