Why can't a helicopter fly in the mesosphere layer?

For the same reason a normally aspirated aircraft can't-the air is too thin. Helicopters run out of lift at a relatively low altitude, and although aircraft can fly a lot higher, they still can't reach 100, 000+ feet. read more

The other answer is correct, Helicopters do fly in the troposphere. For those who don’t know, that is the lowest layer of the atmosphere and it is where almost all aircraft fly. To get even more specific, helicopters fly low, slow, and for relatively short distances. read more

The air in the mesosphere is too rarified for plane wings to generate lift and also to create the proper air/fuel ratio mixture for internal engine combustion to occur. read more
