Remember seeing this done on a Brit atbournemouth.
I think that when start was selected the first thing to happen was the blade angle changed from fully fine to a slightly courser pitch which would then cause the prop to revolve backwards with a tail wind.
I've held a PT6 prop with the engine running when we were trying to locate an oil leak. Held it before start and leaning shoulder against it.

Probably just as well, if that's all that's holding the engine on.

Considering how many B747 freighters were conversions from pax aircraft, wouldn't they have retained the fifth engine pod capability?

tonytales: all the large fan engines will go into freighter aircraft via the nose or side cargo doors.

It wouldn't have been disabled (the pickups will still be there), but in common with passenger 747s, the capability is rarely used nowadays because the likes of an An-124 can be used to ship an engine much more simply.

I'd love to have seen TWA's Packet!

She hasn't flown since 2006, but she's back in her hometown as a resident of the Hagerstown Aviation Museum.

Original plan was to use the ex Farnborough Beverley which sat unused/unloved at Luton for several years because the instigators of the plan went bust.
Now that same Beverley is being evicted from Fort Paull (having been flown to Paull airfield initially) and will probably be scrapped.
