Embraer EMB-145XR (N12195)

A "Wayback Machine" pic from 2008, this click captured N12195, wholly owned and flown at that time by the independent airline ExpressJet, with thrust reversers deployed as it begins to decelerate after landing on RNO's runway 16L.
N12195 is still flying today, but it has changed hands. Today, it is part of the CommutAir (UCA) fleet and flies wearing United Express paint.
As for ExpressJet Airlines, it, too, has undergone change since this photo was taken. In 2010, two years after this shot, Atlantic Southeast Airlines acquired ExpressJet Airlines. Per the results of an employee vote, the new airline retained the Atlantic Southeast callsign, "Acey," but decided to drop the Atlantic Southeast airline name and use ExpressJet instead (similar to the way US Airways acquired American Airlines and then decided to use the American Airlines name even though it was US Airways that had absorbed American).
