There's a really interesting thread on the B&G from Roberto about the number of UPS retirements.

According to him (correct me if I'm wrong Bob):

Retirements from the most recent seniority list compared to the Aug 08 list: 77

Age 65 in remainder of 2009: 6

Age 65 in 2010: 26

Age 65 in 2011: 45

Age 65 in 2012: 48

We retired three fleet types of three-man airplanes in the last two years, and our last new hire class here at UPS was November of 2007 (almost two years ago.)
