Hi,
I am building a diorama with a 1/48th scale B-17 at low altitude. It will have two engines turning and two shut down. My question is, would a B-17 have its landing flaps deployed at all at this lower speed and altitude if it was not landing, just hedge-hopping home? And if so, how much? Thanks, Walt |

Subject: B-17s at Low Level

Thanks, Walt I would doubt it. Flaps are designed to let you fly slower but increase the drag tremendously. If an airplane is crawling home wounded on less than full engine power, drag is the last thing you want. AFJ Unless of course the hydraulic system has been shot out in which case both flaps and landing gear would be down. As I vaguely remember it that hydraulic sytem in a B-17 worked off one engine.I don't remember which one. But I might be wrong about that, Check with a guy who flew B--17's to be sure. But you could justify showing it with wheels and flaps down if an engine is shut down. You might add a trail of smoke for reality. How about a red flare or two fired from the B-17 to show wounded aboard?

I have zero hours in a B-17. My memory fails on that subject. What group did you fly with? ETO or PT?

. As I vaguely remember it that
hydraulic sytem in a B-17 worked off one engine. That was the Lancaster, Art. One of the virtues of the Fortress so far as battle damage went was that it relied so little on hydraulics for the flight controls. Walt |

Dale, with some time on them I'm sure that you'd agree that when limping home on two engines having your flaps or gear down would very likely ruin your chances of ever getting home, right?. -- -Gord. |

At the weights I flew the airplane it performed fairly well on two engines, even so why stack the deck against yourself by adding drag. G On a hot day, or high field elevation having the gear/flaps out could certainly make a difference in the outcome. There was a bunch of discarded ammo and .50s from the continent to England for a reason. G -- Dale L.

pretty much but it would depend on what altitude you were at and how far
away you were form home, i've read a few instances where they were just on the other side of the channel and made it; maybe not to their own base, but to somewhere like manston, or woodbridge or bellied in on a field.
