If this guy’s fuel planning skills were as good as his water landing skills, the plane might have come through. A pilot was delivering a plane, a twin engine Cessna 310G, from Monterey, California to Hilo, Hawaii, when he ran out of gas:
Thanks to the wonders of these modern internets, you can see that a few days ago, he tried the same flight and had to turn around. Here is the track of the actual flight. He almost made it, crashing into the water just short of Hilo.
Specs suggest a Cessna 310G shouldn’t be able to fly to Hawaii. I’m guessing there must be some kind of spare fuel system you can rig up to essentially turn the thing into a flying gas tank. I guess it’s cheaper to fly the plane than to ship it, but I’m also guessing that particular fact wasn’t countered with the high probability of having to ditch the plane in the drink if, despite all your modifications, you’re still really tight on fuel and maybe had a bit more headwind than you accounted for starting out.
