One day in a Lear Jet descending out of FL410 I leaned over to balance the fuel with the FO hand flying, that was in the days you could fly by hand, and when I looked forward I notice our airspeed was approaching red line, my attitude indicator showed a right 30 degree bank and increasing and we were turning right. I cross checked the other two attitude indicators and they agreed so told my FO I have it and leveled the wiings in the clouds and it took every bit of concentration to not follow my instinct to go back to what felt level. I was actually leaning sideways to feel right but still trusted the instruments. In this case however the IAS was wrong and needed to be disregarded. Recent Airbus Pitot static problems with other flights would not let me trust the airspeed instruments in this case. I can't believe anybody would certify an airliner that is stalled but the stall warning mutes because the pitot static system senses less than 60 knots. That is nuts.
