According to thr FAA, the pilot was talking on a cellphone to a friend in a boat below and asked the friend to shine a flashlight in the air to signal the boat's location. If he is dead, he may qualify for a Darwin Award. Definitely. I saw this on the news and thought, oh no, here's another tragic GA accident situation that's going to further polarize the public about the inherent dangers of general aviation. This is all we need, with user fees, TFRs, you name it. Not to mention convincing my own relatives that it's not a dangerous avocation. Then I hear these details and I admit the final story is not in yet, but it sure sounds like some bozo just being totally stupid. We don't need that. Nevertheless, condolences to the families. I think I read it was a Diamond with two on board, both presumed drowned in deep water. Mike |

If I remember right, nobody reporting on the incident reflected on what they
might have done, only on what they actually did. They very well might have optimized range at altitude. Maybe they couldn't get to altitude.

I remember seeing the story but don't remember much about the specifics, and that's where the answer will be I'm sure. Through the fog I seem to remember something about not wanting to do the climb because of the fuel remaining and that being a factor in their decision. Knowing the gang on this forum, I'll bet someone finds the answer before this thread is finished :-)) Dudley Henriques |

Can you have "ground effect" over water? There's a great story about the crew of a Pan Am Stratocruiser I think it was, who were low on fuel and a long way out over the ocean. They let down to within a wingspan's distance over the water, leaned it back a ton, played with the RPM, and made it home. Can't remember the source of the story, but I do remember reading it a long time ago. Dudley Henriques Maybe a true story but I think the the odds are they would have been much better off at high altitude. As I understand it, induced drag is only reduced by 10% at 50% of wing span above surface. At 20% of wing span altitude the drag is still ~70% (Surface skimming birds actually go lower, nearly touching the water with their wing tips). Of course if the Stratocourser dropped to say 10' it could have worked better... -kersplash! Cheers MarkC I recall the story -- happened about 50 years ago. The Stratocruiser lost 2 engines, IIRC, and descended (power glided) to about 1/2 wingspan of the water and was able to fly to land in surface effect. They obviously did not descend immediately, rather they did a max L/D powered descent until they stopped losing altitude. It was written up in an old "Reader's Digest," among others. |

This sounds like the Ernest Gann novel 'The High and the Mighty' which was also made into a movie of the same name, starring John Wayne and Robert Stack. Halfway between Hawaii and San Francisco, they lose an engine which sheds parts and punctures the fuel tanks on that wing. The movie was unavailable for years due to a dispute with Wayne's estate, but has recently become available. I watched it last year, and it is very well done, and the inspiration for all the other aviation disaster flicks. John -- John Clear - http://www.clear-prop.org/ |

John -- John Clear - http://www.clear-prop.org/ If I remember right, in that movie the bird was a DC6 and I think they stayed at altitude until approach with a normal enroute altitude profile. The big rub was the ongoing interaction between the right and left seats on whether to ditch in the sea under power with the remaining fuel or try for the approach and take a chance the engines would quit. Poor Lennie the navigator screwed up his winds and made the problem a bit more interesting, but I don't recall them leaving their assigned altitude enroute to take a shot at ground effect. Great movie though. Wonderful sub-plots with Alexis Smith and David Brian and the other regulars. You have to love the Duke! Poor Robert Stack. With an engine hanging off the wing, raw fuel pouring out all over the place, the passengers yelling and screaming in the back that they're all going to die, solid IFR, on vectors to the FAF with nothing but the city below him and the fuel gauges on empty, the Duke, who KNOWS that unusable fuel just MIGHT be usable, slaps him in the puss and hollers, "Shut up and fly!" Ah...the movies!!! Great Stuff!! :-)) Dudley Henriques |

Dave Esser did a great article on this at ER.

I remember them dumping everything they could overboard since they couldn't maintain altitude, and then arguments over running flat out as far as possible, or leaning aggressively. I don't remember them in ground effect, except for barely clearing Portola Ridge on approach into San Francisco. John -- John Clear - http://www.clear-prop.org/ |
