Yes, that's an airliner smiling. The plane is a Lockheed L-1011 Tristar, arguably the best of the original widebodies. The airline is Pacific Southwest Airlines, the legendary San Diego based passenger carrier better known as PSA. The smiley face was part of its livery, which tells you something about PSA's corporate culture. Growing up in the West San Fernando Valley in the '60s and '70s, Lockheed and PSA were part the air.
Lockheed no longer makes airliners and PSA was swallowed up by USAir (now US Airways). Nowadays "PSA" usually means "prostate-specific antigen" and it is an indicator for prostate cancer -- which was discovered in me during the autumn of 2007. I had a prostatectomy right after Easter of 2008, and after that guys have their PSA tested regularly. Yesterday morning I got the results of my latest PSA:
Less than 0.1.That is, immeasurable.
Alleluia! Still right where we want it!
As PSA's ads said, "Catch our smile!" (Besides, can you think of a better graphic?)
