less oxegen levels and air pressure.
Most airplanes fly at high altitude because it is faster and safer as long as the cabin is pressurized. There is less clouds and turbulence. The airplane uses less fuel.
At high altitude
Spaceships are MUCH faster than airplanes.
One of the main reasons is to conserve fuel. Airplanes can fly at any altitude and speed. However, airplanes generally tend to fly at high altitude to conserve fuel. This makes the plane more efficient and keeps the operating cost down. Of course, an airplane can not always fly at max altitude at every flight. It may have too much weight or the distance it travels may be too short. So there is always a trade-off as to how they will fly the route.
Yes, jets really are airplanes but they are faster airplanes.
From 28,000 to 33,000 feet.
36,000 feet
Yes.
No. Airplanes are faster.
Speed, altitude, and cost.
Altitude sickness occurs when people increase altitude too quickly. What is the cause of altitude sickness? Acute mountain sickness is caused by reduced air pressure and lower oxygen levels at high altitudes. The faster you climb to a high altitude, the more likely you will get acute mountain sickness. You are at higher risk for acute mountain sickness if: You live at or near sea level and travel to a high altitude. Oct 16, 2017
