The 727 was the first jet that I flew. It was nice most of the time. It was possible to grease it in but also I have had my worst landings in that airplane too. Normally that happened after a very stable approch in perfect weather. I never understood what I did wrong. Some captains told me to push the yoke forward during the flare. That worked fine some of the time but not always. The next one was the 747. I fell in love with that one immediately. It was always consistent.
