As a co-pilot my mate and I once over-indulged "The Lunch Time Beer" that one might partake of to assist the afternoon sleep prior to a nighttime departure.
We didn't consider ourselves drunk, but we sat at the back of the crew bus to avoid conversation, and when on the aircraft my mate, who's sector it was to navigate pulled up the curtain at the Nav. table and imbibed 100% oxygen,whilst I dictated the check list in the right hand seat as carefully as I could and avoided direct chat.
The Captain started up, pushed back, taxied out, lined up on the runway, then quietly said - You have control.
After I'd fought the beast to top of climb and engaged the autopilot, he said - You won't do that again, will you ?
I didn't.
