you flew was a former Lufthansa 727-030 which also had that switch configuration
Oh god, you're asked my brain cells to wake up. If we did end up with that aircraft, I sure don't remember the landing lights switches being opposite on one aircraft from the other two.
We only received one 727 (N27) from the FAA, the other two (a 100 and a 200) we bought. N 27 was the one that was involved in the midair with a Cessna 172 when it was still with FAA, if that helps.
We did dry lease quite a few 727s during the years I was there and I do remember one was an ex-TWA bird. Also, we leased one that was the old Hoot Gibson aircraft, that aircraft wanted to fly sideways more than it did straight.
Wait a minute, that was the one. It was the former TWA 727 that we flew for a while.
