That this isn't even the worst airplane-related misunderstanding by a major presidential candidate this election cycle. Wondering why the windows don't roll down is much less bone-headed than thinking an unmanned airplane has the power to turn Pakistani men 16 and older into enemy combatants just by bombing them.
Sounds to me like someone was pulling your leg and you didn't get it.
"If there is an autopilot, why are their pilots in the cockpit?"
Anyone actually saying that is joking.
