An interesting look back: it's a copy of a Tracor ad showing someone
carrying a portable Rb clock down the stairs of a PSA plane. Lots of
history in that photo: no jetway, PSA, people wearing coat and tie on an
airplane. Even the street name for GTC, on Bellanca Av, redolent of
long-gone airplane mfrs.. BTW, google street view shows a building that
is probably where Tracor was. (in among a bunch of giant parking
structures, of course)
At the address is now Secom International - a leader in parking solutions.
