The Push/Pull throttle thing reminded me of the difficulty I had when I first started flying.
I had worked for many years on fire engines and generators, in fact any static engine using hand throttles it is 'Pull' to increase, 'Push' to decrease rpm. It felt wrong to do the opposite in an aircraft.
An instructor explained to me the reason it is 'Push' to increase in an aircraft is because you want all the knobs 'in' when flying, not pulled out, it's safer and there's less to get in the way. Made sense to me.
