The co-pilot and flight attendants were trying to lift up the carpet in the exit row, apparently to find a floor window which would give a view into the cargo hold. No such luck. The carpet had recently been tacked down to the floor when this particular aircraft underwent some renovations. Unfortunately, no consideration had been made for the floor window in case of an emergency, such as we were presently experiencing.
