From 28,000 to 33,000 feet.
No, microwaves are not available on airplanes for passenger use.
If a commercial passenger jet can travel up to 970 km per hour at an altitude of 30,000 feet, it would take just under 3 hours to travel 2,902 kilometers.
Passenger airplanes
Most aircraft do not travel in the stratosphere. Some military and passenger jets fly in the stratosphere, but most aircraft fly in the troposphere, below the stratosphere.
36,000 feet
Speed, altitude, and cost.
Passenger airplanes typically fly at altitudes between 30,000 and 40,000 feet (about 9,000 to 12,000 meters) during cruise. This altitude range allows for optimal fuel efficiency and reduced air resistance. Commercial jets are often pressurized to ensure passenger comfort and safety at these heights.
It varies. Normal commercial airplanes travel at approx 500 km/hr. The fastest ones can reach Mach 3-4.
To travel
To see the curvature of the Earth, you would need to be at an altitude of at least 35,000 feet, which is roughly the cruising altitude of commercial airplanes.
The altitude needed to see the curvature of the Earth is typically around 35,000 feet or higher, which is the cruising altitude of commercial airplanes.
Yes, cellphones are allowed on passenger trains, unlike airplanes.
