The fastest passenger plane in 1955 was the DC7. It flew at about 375 miles an hour, however, it could fly faster than 400 miles an hour. Most airplanes flew faster than 300 miles an hour.
Most passenger airplanes fly in the stratosphere. Planes like Cessna fly near the troposphere. It depends on the size and sound of the planes.
Only for short periods.
Domestic planes typically fly at speeds ranging from 500 to 600 miles per hour.
Planes fly about 80 to 100 miles per-hour.
Passenger planes can't fly at 55,000 feet. Gulfstream business jets can fly 51,000 feet altitude, and airliners like to cruise at 35,000 feet. Some military planes, like the U-2, can fly at 55,000 feet or greater.
It depends on where the engines are if its on the wings then no
by using lots of fuel and by going very fast.
Only jet fighter planes break sound barrier now.
Of course, planes can fly.
Whatever plane was available for operation, or the plane that the pilots were assigned to fly.
It depends on the plane. Some private/borderline ultralight planes only have a range of 100 miles or less, while commercial planes can fly across the Atlantic.
about 357 km or 222 miles depending on the visual acuity.
