In the air.
Most commercial planes fly in the troposphere, which is the lowest layer of Earth's atmosphere and extends up to about 7-10 miles above the surface. This layer contains the majority of the Earth's weather systems and is where most commercial airliners operate.
LOL they can fly in planes. Women are famous for being Cabin Crew
Yes.
No, commercial planes are not designed to fly inverted and doing so would pose a significant safety risk.
Planes are not perfect but they are not the worst to fly in because it can be safe but it cant be sometimes most of the time it is great to fly in so most of the time planes are safe.
In the air.
Every airplane has its own speed limits. Most small and commercial planes fly below Mach (the speed of sound). Military fighters and some other planes, like Concorde, fly above Mach, or supersonically.
It’s 45,000 ft for commercial airliners
About 8-10% of Americans fly on planes daily. This is about 1.73 million flyers each day. Passengers, however, are not just relegated to large commercial flights. In fact, the percentage includes individuals that fly on small commuter planes, helicopters, and even private planes daily.
Most passenger airplanes fly in the stratosphere. Planes like Cessna fly near the troposphere. It depends on the size and sound of the planes.
Of course, planes can fly.
any plane you want as long as people aren't in it
