it makes sense to me that the pilot who said "I did not do it" actually did do it without realizing it, was supposed to be putting the landing gear up when he committed a muscle memory mistake. it happened around the time the landing gear should be up, and this explanation matches what was said in the cockpit, and the fact that the landing gear wasn't retracted. I think this idea was even floated initially by the you…
There is no possible way to confuse these two actions. There's a reason a wheel is attached to the gear lever.
Weird mistakes can happen.
My partner got a good laugh out of it
