There appears to be a recent reliability problem with the Trident. There seem to have been at least two failures in the past 35 launches. Lockheed often issues press releases after successful tests. Up until 2012, with the 135th, all of their press releases talked about the "XXXth consecutive successful launch." Starting in 2012 with the 137th, they all say "the XXXth successful launch." I take this to mean that #136 was unsuccessful. Their latest release talks about the 161st successful launch.
