Probably fodder for a separate thread, but the 727 had a reputation for hard touchdowns if power wasn't kept up through the flare. A whole separate "Tech-Log" debate in itself, but one of the reputed reasons was that the massive triple-slotted flaps could kill airspeed so fast that an unpowered flare simply turned into a 5-foot free-fall.

I guess it depends on which market one is flying in, but it would surprise me if there were many 727 pilots still transitioning to 737s (and bringing along old habits) at this late date.
