Typical sink rates at touchdown are on the order of 2 to 3 feet per second, and even a “hard” landing rarely exceeds 6 feet per second.

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.
Can a large modern jet airliner plunge intact underwater from flight? No.Large airliners are not desgned for this and are not even strong enough to make a landing on water in less than perfect conditions.
“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.
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.
So it is better to crash on land. As a light aircraft pilot, I can try to answer a more specific question: if your aircraft has a total engine failure, are you more likely to survive over land or sea? And the answer to this is that, generally, you are much more likely to survive over land.
8 May 1978: National Airlines Flight 193, a Boeing 727 Trijet, unintentionally landed in the waters of Escambia Bay near Pensacola, Florida after coming down short of the runway during a foggy approach.
Applying this 1 percent rule would result in an airline pilot being denied a medical certificate if their risk of a medical incapacitation (e.g. heart attack, convulsion, stroke, faint etc) was determined as being greater than 1% during the year.
An aircraft lavatory or plane toilet is a small room on an aircraft with a toilet and sink. They are commonplace on passenger flights except some short-haul flights. Aircraft toilets were historically chemical toilets, but many now use a vacuum flush system instead.
It depends on the plane. Some aircraft have the ditching qualities of a submarine and may sink within a minute, while others may remain over the surface for hours.
Very good, IF you are prepared. A ditching is an intentional water touchdown under control, not an uncontrolled crash. Of the 179 ditchings reviewed, only 22, or 12 percent, resulted in fatalities. The overall general aviation ditching survival rate is 88 percent.
With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing.
What's the slowest a plane can fly? The Ruppert Archaeopteryx has a certified stall speed of 30–39 kilometres per hour (19–24 mph). The Vought XF5U can fly as slow as 32 kilometres per hour (20 mph). The Tapanee Pegazair-100 stall speed is 45 kilometres per hour (28 mph).
Some years ago, when Captain Chesley B. Sullenberger (Sully) landed US Airways flight 1549 onto the river Hudson, the lack of fatalities and responsiveness of crew was hailed a miracle. Water landings, whether controlled or not, can be very dangerous, and it's paramount that staff are trained on how to manage them.
Hard landings can be caused by weather conditions, mechanical problems, overweight aircraft, pilot decision and/or pilot error. The term hard landing usually implies that the pilot still has total or partial control over the aircraft, as opposed to an uncontrolled descent into terrain (a crash).
You may think the life vest under your airplane seat will save your life if the aircraft ends up in the water. In fact, such a thing has never happened in modern commercial airline flying.
Commercial plane crashes are nowadays very rare, with approximately 45,000 flights typically completed each day in the US, all without fatality. That's a number that continues to rise, post Covid.
If anything goes wrong, the likely result is a runway accident, which can have deadly consequences. According to a study published by Boeing Commercial Airplanes, nearly half of all aviation accidents occur during the final approach or landing and 14 percent occur during takeoff or initial climb.
Most of the survivors were sitting behind first class, towards the front of the plane. Nonetheless, a TIME investigation that looked at 35 years of aircraft accident data found the middle rear seats of an aircraft had the lowest fatality rate: 28%, compared with 44% for the middle aisle seats.
