The recent water landing into the Hudson is still being investigated. This AP article focuses on whether flight attendants were trained not to open the back door of the plane during a water landing, but the most interesting bit comes at the end:
Another concern is whether the FAA and airlines need to revise emergency procedures for pilots in the event both engines fail. Those procedures usually involve a sequence of many steps called a checklist. There are different checklists depending upon the problem, but most are based on the expectation that the problem will occur while the plane is flying at a high altitude — airliners typically cruise above 20,000 feet, giving pilots time to identify and correct the problem.
Flight 1549’s first officer, Jeffrey Skiles, told a congressional panel in February that he only had time to make it part of the way through a checklist for restarting the engines when Sullenberger sent the plane into the river.
Sumwalt suggested it would be better for airlines to train pilots to remember one procedure for a low-altitude dual engine failure, rather than go through a long checklist of items while altitude rapidly diminishes.
