How fast would an airplane sink?

Some aircraft have the ditching qualities of a submarine and may sink within a minute, while others may remain over the surface for hours. Sometimes moments, sometimes weeks. Depends on the the degree of damage from impact. Landing in rough seas would pretty well destroy the aircraft.

A: A busted plane in one piece is likely to glide up to 100 miles from 30,000 ft. A plane in pieces falls with a speed related to its weight and its surface area. A piece that has a square foot of surface for each 45 pounds of weight is likely to fall at about 120 mph; slower if it flutters.

When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.

“A water landing in an aircraft that is in 'out of control flight' (OCF) would most likely be unsurvivable.” So whilst some flights may be able to survive on water, it is all dependant on the problem with the flight and how far out in the water the passengers are from help.

Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman.

Reflecting this increase in miles flown, preliminary estimates of the total number of accidents involving a U.S. registered civilian aircraft increased from 1,139 in 2020 to 1,225 in 2021. The number of civil aviation deaths increased from 349 in 2020 to 376 in 2021.

All airplanes will be exposed to drag during flight. They must overcome this aerodynamic force to achieve and maintain lift. Otherwise, airplanes would essentially fall out of the sky. Air brakes are control surfaces that increase drag so that airplanes slow down during flight.

In the steady motion of an airplane traveling at cruising speed, there is no discernable acceleration, so there is no “motion” to feel. Why don't you feel how fast you're traveling in an airplane? We don't feel motion per se. What we feel is acceleration or changes in speed.

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.

The NTSB says that despite more people flying than ever, the accident rate for commercial flights has remained the same for the last two decades, and the survivability rate is a high 95.7 percent.

Whether it would be safer to crash on land or water would depend on the choices available. If the misfortune happens near land and water, I would crash land on a dry, flat and hard surface. If my choice is only the river amidst the high-rise buildings, I would opt for ditching.

22 October 1962: Northwest Airlines Flight 293, a DC-7C with 7 crew and 95 passengers made a successful water landing in Sitka Sound.

In jet aircraft, an overspeed results when the axial compressor exceeds its maximal operating rotational speed. This often leads to the mechanical failure of turbine blades, flameout and total destruction of the engine.

Weight Focused On The Nosewheel Transferring too much weight onto the nosewheel causes a situation called wheelbarrowing, which can lead to a loss of directional control, prop strike, or nose gear collapse. On top of those problems, with little to no weight on your main landing gear, you have little braking action.
