Find the answers to the “Microsoft Rewards Bing Warpspeed Quiz” for 4-14-2025. Discover amazing flying machines and their surprising uses throughout history.
Question 1: What makes an ornithopter unique?
- It flaps its wings
- It has no wings
- It uses no fuel
Answer: It flaps its wings
Fact: An ornithopter is unique because it flies by flapping its wings, just like a bird or an insect. Unlike airplanes that use engines and fixed wings, ornithopters use wing motion to generate lift and move forward. This makes them special among flying machines. Some small ornithopters can even fly without fuel, using batteries or rubber bands instead.
Question 2: Which flying machine uses a fan for lift?
- Hovercraft
- Zeppelin
- Hang Glider
Answer: Hovercraft
Fact: A hovercraft uses large fans to blow air underneath it, creating a cushion of air.
This air cushion helps it lift off the ground and move smoothly over land or water.
Unlike airplanes or gliders, it doesn’t need wings to fly a little above the surface.
Zeppelins and hang gliders use other methods like gas or wind for lift, not fans.
Question 3: What aircraft uses human-powered flight?
- Gossamer Albatross
- Concorde
- Biplane
Answer: Gossamer Albatross
Fact: The Gossamer Albatross is the aircraft that uses human-powered flight. It was powered by a person pedaling, like riding a bicycle. The energy from pedaling turned the propeller to make it fly. This aircraft flew across the English Channel in 1979. The Concorde and biplane are powered by engines, not humans.
