In GI-Joe TPB Vol 2, Dr Venom jump starts an old Lancaster bomber that has a burnt out inertial starter on the port inboard engine. He feathers the blades on that engine and then builds up speed on the ground with the other three engines, generating enough of an airstream to kick over the dead engine when he unfeathers the the prop on it manually and cuts in the fuel injection system. It works! I was just wondering if something like that is theoretically possible. It sounds plausible enough, and makes for a great comic story. Does anyone know?

Bob Morgan did something similar to that in the Memphis Belle.

One engine wouldn't start, so he kicked everyone off the plane, nearly burned the other 3 out on takeoff, started the inop one in the air, then landed and picked everyone up. It was strictly against regulations, but they made it to their dance that night.

You can find this account in many many books.

The procedure is called a "buddy start".
It can be done with all models of the C-130
except the C-130J.

What is required is that your props have electric
control, or in the case of the C-130 electric aux pumps.

The prop is set to aproximately 45 deg blade angle
and the other plane is positioned as close as possible
in front. There is enough air flow to spin up a T-56
turbo prop to 30% and allow it to run! It is an accepted
emergency start option. Taking off with a feathered
prop is permitted but you need a lot of runway.

As to the lancaster, I doubt it. I am not aware of those
props being able to change pitch with the engine off.
To the best of my knowlege they had no electric assist.

The story about the Memphis Bell sounds fishy as well.
Those Hamilton standard props had no electric aux pumps
and depended on engine oil pressure to operate. You would
have to take off with an un feathered engine, that's suicide.
