In 1978 when I was working in Pensacola we had this National 727 land in Pensacola Bay. He was on approach and had his gear and flaps down and was at landing speed and at 520' at 5 miles out when he mistook a barge lights for a wet runway. There was heavy rain at the time and no ILS (Instrument Landing System) to runway 27 for his approach. The aircraft remained intact and everyone but 3 survived who had drown, the survivors were rescued by the barge. They actually floated the plane and took it away on a barge and sold it for $1 million to a refurbishing company. It was in the bay for about a month and was very visible when crossing the I-10 bridge. Needless to say, National was in a hurry to get it removed. National went out of business two years later in 1980.
