How long would it take a plane to sink to the bottom of the ocean?
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.

22 October 1962: Northwest Airlines Flight 293, a DC-7C with 7 crew and 95 passengers made a successful water landing in Sitka Sound.
Most flights are intended to spend as little time as possible over water, since storms are more common over the ocean than on land. An aircraft would not be safe to fly over the Pacific Ocean due to the stormy weather and frequent lightning strikes that occur there.
Because of its vast size, crossing the Pacific Ocean requires a staggering quantity of fuel. However, most commercial aircraft do not fly directly over the Pacific Ocean; instead, they choose what are known as 'curved paths'. These paths offers a faster, more efficient route given the curved nature of the earth.
When flying over land, of course it is more likely that there will be more airfields closer to the aircraft at any given time. However, because of lessons learned from its history and the improvements in aircraft and engine reliability, crossing the oceans is deemed as safe as flying over land.
United flight's plunge toward the ocean was caused by pilot error, NTSB says. A 2022 incident where a United Airlines flight came within 748 feet of crashing into the Pacific Ocean was caused by pilot error, federal investigators say.
The good news is that pilots are supposed to dump fuel at a safe height above the ground and away from other aircraft, and in addition, over as remote an area as possible. In the case of Heathrow, for example, most fuel dumps have occurred over the sea.
No.There is no mechanism that allows the crew to dump the contents of the lav holding tank. It is possible that a fault in the system could result in waste going overboard, but such incidents are very rare. See What happens when you flush the toilet on an airplane?
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.
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.
If the aircraft is partly submerged, you may have to wait for the cabin/cockpit to fill partially with water to allow the pressure to equalize before you are able to open the doors. For many, the most difficult part of surviving a ditching accident is an underwater egress.
Thanks to the low visibility and undeveloped infrastructure, flying over Antarctica is extremely difficult. Specifically, because of the strong magnetic fields that surround the polar regions, navigating there, no matter how well-equipped the airplane is in terms of instrumentation, can be particularly challenging.
What is the longest flight in the world by distance? The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles. What plane can fly the farthest in the world?
Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
