Can a plane take off while moving backward on a conveyor belt?

Image
In a classic MythBusters episode, Adam Savage and Jamie Hyneman attempted to answer the age-old question:  Can a plane take off while moving backward on a conveyor belt?  To their surprise, the plane was able to lift off successfully, even though it was moving in the opposite direction of the belt's motion. To understand why the plane was able to take off, it's important to consider the principles of flight. Airplanes generate lift by moving over the air, causing the air to move downwards. This downward force, combined with the upward force of the plane's engines, allows the plane to overcome gravity and take off. In the MythBusters experiment, the conveyor belt was moving at the same speed as the plane's wheels, effectively canceling out any forward motion. However, the plane's engines were still generating thrust, pushing air backwards and propelling the plane forward relative to the air. This forward motion was enough to generate the necessary lift for takeoff...

"The Baddies"

Once upon a time, in a land far, faraway, there lived three mischievous characters: Donald Trump, the ghost, Mark Johnson, the troll, and Marjorie Taylor Green, the witch. They were known throughout the land as "The Baddies" because of their penchant for causing chaos and mayhem. Trump, the ghost, was a bit of a show-off.

One day, he disguised himself as a statue and stood in the middle of a busy intersection. When people didn't pay him any attention, he would let out a loud roar and scare them half to death. Marjorie Taylor Green, the witch, was a bit of a klutz. She was always tripping over her own feet an...
