That is why it is important to have your own mental checklist lining up for takeoff, flaps set and speedbrakes retracted, and landing gear and flaps for landing. Quite simple and eliminates checklist mishaps. I had the Madrid fault happen to me in an MD80 because of a nose gear strut overinflation making it put us in air mode taxiing out with the strobes flashing and no TOWS operative. Sometimes things don't work as they should so take care of yourself. Especially in an MD80.
