Have a look at this link to see fabulous WW1 aircraft started by ModelT fitted with Hucks starter
Great photos! Thanks for the link.
I didn't see a picture of anybody doing it, but it looks like the pilot would have to stand up to use the machine gun mounted on top of the wing.
Steve that was before they installed interrupters to stop the machine gun from putting bullets in the prop (I'm told that was bad) so they had to mount the machine gun to fire outside of the proparc. BTW the first interrupters were only tested on the ground until they got the timing right.
Some of the early "over the wing" setups may have required you to stand up to reload or clear jams, but I believe there was a cable or linkage to allow the pilot to fire the gun from his seat.
Later on, the "Foster Mounting" was developed, which allowed the pilot to pull the gun down a trackway to make it easier to reload and clear jams, here is a photo of a pilot loading a fresh ammunition drum onto his Lewis gun:
Wow! That looks about as risky as texting and driving is today. Wonder how many drums were dropped? :-( Neat photo Mark.
