This is probably one perk to the way that John hooks his plane up. I've
always handled my plane from the left side, but John handles his from
the right. This way he can push the blast shield toward himself rather
than hooking up, pulling the shield out and launching as I do. I'm
thinking about making finger supports so that I can use both middle
fingers to push the shield off.
