Cessna Citations are not the most exciting business jets. The original versions are particularly uninspiring with their simple design and unswept wing. Normally I might not even bother if I came across one. This example showed up at Davis Monthan while we were on the ramp and it obviously wasn’t a standard version. It belongs to the Customs people. I imagine it spends a lot of time looking at what is going on along the border. Flying out of Tucson would support that idea. I imagine the sensors on board are a lot more interesting than the plane itself.
