My dad flew the L-1011 for the big airline in the southeast (that's still in business). He instructed on it too and I was fortunate enough to get quite a bit of sim time in her. What a fantastic airplane. He used to let me sit on the engineers seat and act as a quasi engineer to the guys up front, reading checklists and telling them stuff that was wrong with the plane to prompt them to do stuff. Super neat. I remember just two things distinctively...HAT in the window (Heading/Altitude Select/???) and the DLC and MDLC. Any airplane that you can get into the pilot seats from either side is pimp in my book.
