I used to fly a B-52 for the USAF.
8 engines, 6 gauges each, 10 hyd systems with gauges, fuel system had 16 tanks, electrics had 4 generators, oxygen system had 2 systems, landing gear 6 lights, 2 navigation radios, 3 voice radios, intercom, autopilot, bombing system, missle system, air conditioning system, emergency alarm system, ...
Never got asked about my gauges though

I think I would ask them why they drive "blind", oh, opps, they do have an IDIOT light!
