## How long does it take for an airplane to hit the ground?

It all happens so fast. From the moment you’re outside of the plane, it’s only about 170 seconds until you hit the ground. During that time you will be extremely cold, and deprived of oxygen. The average temperature at 9,144 meters (30,000 feet) in the sky ranges between from -40° C to -57° C (-40° F to -70° F).

## How fast do planes sink?

Stay calm, a properly-ditched aircraft will take over five minutes to sink.

Is it possible to survive falling from a plane?

There have been some incredible instances of people falling out of airplanes without parachutes and surviving. Take the story of Alan Magee, an American airman who survived a 22,000-foot fall from a damaged B-17 bomber over France in 1943. Remarkably, Alkemade only suffered a sprained leg after falling 18,000 feet.

### What do planes do if landing gear fails?

When an aircraft is unable to touch down with its landing gear fully extended it must perform a gear-up or “belly” landing. Such a landing does carry a small risk – there is likely to be damage to the aircraft; it could conceivably catch fire or flip over if it lands too hard.

The time an actual aircraft takes to impact the ground only takes a few milliseconds. What transpires that leads up to the crash can vary from seconds to even, potentially, hours. For example, an aircraft might be flying in conditions of limited visibility and suddenly a mountain appears as the aircraft impacts the mountain.

### What happens when a plane loses its engine?

While losing an engine sounds scary, it was the loss of air pressure that placed the plane in greater peril. Human beings can’t survive long without air, and passengers’ drop-down air masks provide only enough oxygen for about 12 to 20 minutes.

How long can a plane fly with one engine?

In the case of the engine loss itself, the problem was not all that dire. In fact, airliners can fly quite well on just one. The Boeing 777 is certified to fly up to five and a half hours with one engine out. With less power, a plane will be unable to maintain its maximum altitude, and so might drift down somewhat into thicker air.

## How long does it take to jump out of an airplane?

If you were to jump out of the plane and immediately reach terminal velocity, it would take about 2 minutes and 48 seconds to reach the ground. Now, our airplane has a faster terminal velocity, but would also take a bit to get up to that speed.
