They fly in air.
High-performance military fighter jets have engines powerful enough that they can
fly straight up, like a 'rocket ship'. But aside from those, all airplanes need air in
order to remain aloft.
jets
Jets do, not prop planes.
Stratosphere and Troposphere
I said it is a Astronomer
Yes many jets can travel at this speed as can props
Yes, jets are planes but jets are mostly known as supersonic planes.
It really depends on what the size of the jets. The Airlines fly from 32,000 to 38,000 feet.Normal Jet Planes fly at about 30,000 feetMilitary Jet planes fly anywhere from 100 feet all the way up to 80,000 (Some do go higher but those are for special occasions)
I'm sure that some of them have planes but one driver who really likes to fly airplanes is Carl Edwards.
Most prop planes fly any where from 1,000-5,000 ft. Airliners usually fly from 10,000-20,000 ft. Military jets fly at pretty much any altitude
All planes were grounded. They had to land at the nearest airport and for 3-4 days no planes were allowed to fly. An interesting side note several private jets were allowed to fly Ben Laudin family members to Saudi destinations .
about 357 km or 222 miles depending on the visual acuity.
Jets generally fly at or above the tropopause because below it, in the troposphere, is where all of Earth's weather occurs and it is best to avoid weather complications so they fly above it.
