Well, this is a simulation of something that really did happen to the DC-7C
Irish Sea in late '59. Here's Sarah Carter's description:
We were out about an hour and a half, just over Bristol, England, when the steward came down the aisle informing us that we were on our way back to Schiphol. One engine had gone out. The crew dropped fifteen thousand gallons of gasoline into the North Sea so we could land more easily.
I was sitting next to the window. The water seemed a long way down below and it was cold too. Many a thought goes through your mind in a moment like that. But I knew there was a power to hold us up until we could land safely. So I offered a silent prayer in mid-air. (pps. 172-3)
It's interesting that they were over Bristol because that was the route, via Ireland, that we flew in by. I've simulated the problem over Hull on the Humber, rather than Bristol at the mouth of the Severn. It is also interesting that they felt able to return to Holland, rather than making an emergency landing in England where there were obviously plenty of airports that could have handled it (three hours later and it would definitely have been Gander that they'd have made for!). If you look at the KIAS on these pictures, you'll see that power loss was quite substantial, around 30 knots.
I wonder if he really dumped the fuel in the North Sea? Over Bristol the
Irish Sea airplane was, ironically, much closer to the actual Irish Sea. But she's probably right that they only dropped it later, after the turnaround, to make the landing safer.
We might as well take a quick look round a British airport that came within range of TT before going back to Schiphol. This is Cambridge:
A DC-3 from Derby Airways, now part of British Midland, with a Cessna off to Barcelona in the background. Here's one of those unmarked (MercAir?) ones sneaking from Glasgow, Scotland to Saint Catherine, France, whisky being the obvious contraband cargo:
And a Scandinavian Convair going from Heathrow home to Sola, Norway:
A Cessna 170A:
He's flying from Waterford, Ireland to De Kooy, Netherlands. You can see that he was quite close below us over the North Sea (though we did
not dump 15,000 gallons of fuel onto him):
Coast of Holland ahead. We come back into range of the Neptunes at Valkenburg:
One going on the patrol round, the other off to Eelde.
This is a chance to take a better look at the correct 1963 Valkenburg scenery and - even more exciting - an
improved EHAM '63 (is it possible?) which Harry has sent me! The Carters' misfortune shall prove to the benefit of 21st Century flightsimmers.
