[GreenKeys] AT&T

[John Beckman]

The link below is a 1965 AT&T film based on airline communications at 
the time. It is about 20 minutes long - but it is full of relay rooms 
and model 28s. If you have the time you might find it interesting. It 
also reminds me of simpler times and phones with dials on them.
