In youth-obsessed LA, over 40 is over-the-hill. When it comes to aircraft, this rule still applies. Old NASA Boeing 747-123 is 42 and it was recently put out to pasture -- so to speak.

The majestic relic's final takeoff occurred two days ago from LAX. A YouTube video depicts this aeronautical swan song.
