Could A Plane Take Off On A Backwards Conveyor Belt? | MythBusters
In this episode of MythBusters, the team tests the controversial myth of whether a plane can take off from a backwards conveyor belt matching its takeoff speed, ultimately proving that the plane can indeed take off despite the belt's movement, thus busting the myth.
Watch on YouTube ↗Key takeaways
- Planes can take off even when on a conveyor belt moving in the opposite direction at takeoff speed, disproving the common myth.
- The takeoff speed required for the model airplane was determined to be 11.3 mph, highlighting the importance of speed in flight.
- The MythBusters used a butcher paper conveyor belt to test the myth, showcasing their innovative approach to solving practical challenges.
- The myth's confusion stems from the difference between aircraft and cars; airplanes rely on thrust from engines rather than wheel traction.
- In the final test, a manned ultralight successfully took off from a conveyor belt, confirming that the myth is indeed busted.
- Research the principles of flight to better understand how airplanes generate lift and thrust, especially in unconventional scenarios.

High Level Overview
This experiment investigates the widely debated question: if an airplane is on a conveyor belt moving in the opposite direction to match its takeoff speed, can it still take off? The premise challenges common misconceptions about how airplanes generate lift and whether ground movement alone can prevent takeoff. This inquiry is relevant for aviation enthusiasts, engineers, and anyone curious about fundamental physics and mechanics of flight.
