JetFlix TV founder Henry Tenby filmed this Sierra Pacific Boeing 737-200 action at Tucson’s famous spotters location at the Fedex parking lot in early 2016. The two 737-200s shown in the video N703S N712S and have since been retired and replaced with newer generation 737s, making this footage all the more special. Sierra Pacific is a specialist charter operator that does contract flying for the US Government moving prison inmates between locations as well as government transport of illegal aliens. In earlier years Sierra Pacific operated a fleet of Convair 580s, back in the 1980s and 1990s.
