10 kilometers (about 32,808 feet).
The airplane was flying at a very high altitude.
What a neat little problem ! I'll remember this one, and I'll use it. The altitude to the hypotenuse is 12.0 millimeters long.
50km in height
plane was flying at 650m
I have hiked up to the altitude of 14,000 feet. That airplane will be above the altitude of those clouds.
Altitude sickness most likely
480 kts
From the altitude of the airplane when you jumped out.
The altitude ranges from 30,000 feet to 45000 feet. This is only average altitude. This range is suitable when the plane has levelled.
It depends what aircraft and what speed you are going
Troposphere only
The altitude of the bottom of the troposphere is around 8 kilometers (5 miles) at the poles and 18 kilometers (11 miles) at the equator. The altitude of the top of the troposphere is approximately 12 kilometers (7 miles) at the poles and 20 kilometers (12 miles) at the equator.
