Question

Which is a reasonable explanation for why airplanes cannot fly in the mesosphere

Answer 1

Answer: The air is too thin above that altitude to hold the plane up. Some kinds of planes can fly much higher, and one special NASA plane, named Helios, flew to about 30 kilometers (19 miles), which is far higher than any other plane has traveled. At that altitude, the air is 100 times thinner than at sea level.

Answer 2

Answer:

Explanation:

.The water vapor and dust particles in mesosphere could foul an airplane’s engines. to fly, airplanes need lift provided by air currents, and there is not enough air in the mesosphere to provide this lift. to fly safely, airplanes need to avoid extremes of weather like those encountered in the mesosphere. the mesosphere is too close to the earth, and airplanes flying there would run the risk of crashing into objects like mountains.
