There was a successful ditching back in the early 70s. An ONA
DC-9 was leased out to ALM
Antillean Airlines (the plane was wearing full ONA
colors though). JFK
to STM when it had to deviate around strong thunderstorms and ran out of gas. It went down in huge swells of the Caribbean Sea and remained intact...the evacuation was a nightmare however to the point where one of the life rafts was inflated by mistake in the galley at Door 1R. In fact, the flight attendants were walking up and down the aisles helping people get ready for the water landing when the plane hit the waves...absolutely no communication from the cockpit crew...they were ONA
and the FA
's were ALM
...it was a very interesting sinerio...many lived...can't remember the numbers.
Hope this info helps.
