From wikipedia, Boeing stopped producing MD-11 since 2,000. Does that mean any MD-11 flying is at least 25 years old? I know 25-year is not particularly old for aircrafts, but MD-11 is not exactly reliable. Is there any reason UPS is flying these planes?

Airframes have a limited lifetime, partially defined by takeoffs and landings (and pressurization cycles). Cargo planes experience fewer cycles than passenger airlines since cargo carriers' aircraft usually only make a one or two flights a day, whereas passenger aircraft a flown back to back as frequently as possible. Historically, cargo carriers would buy used aircraft and convert them, but that's changing.

This particular aircraft was acquired by UPS in 2006 and converted for cargo missions. It was originally delivered as a passenger aircraft to Thai Airways International in 1991. [1] I actually saw this exact aircraft at RDU International in August of this year and took a photo, since tri-engine aircraft in general are not very common these days.
