the picture. In effect metadata for chemical based photography. One reason
why I'm probably not going back to doing much work in with film. No Metadata.

That?s a beautiful and fascinating set, Jim. I wish I had a better
recollection of AEDC from my ROTC summer-camp visit there in ?67.
I had a fling with APS too, still have my Canon EOS-IX APS SLR here on
the shelf in my study, and lots of (inaccessible) rolls of developed film in
the drawer. Any idea whether it?s possible still to get these scanned?
The nameplate on the electric motor is fascinating ? 13200 V @ 2750 A!
That means the resistance of the windings is less than 5 Ohms. Given that
there must be hundreds of meters of wire in the windings, the conductors
must have the gauge of a garden hose. With a PF of 100%, the 13200 x 2750 x
sqrt(3) VA works out to some 62 MW or 83000 hp at the shaft.
For comparison, the four MerMaid electric propulsion pods of the Queen
Mary 2 together at full steam draw 80 MW or only about 30% more than what
this motor draws! I?d guess that this motor alone could power the QM2 at the
economical speed with which we crossed the Atlantic in 2013. The ship?s
power plant produces less than twice the power that this motor consumes.
That is one H of a motor!
The ducting for the tunnel looks like any old industrial stuff?until you
notice the gauge of the steel stock, and the sheer number of bolts on the
flanges. That was built to take SOME pressure!

In reviewing my images from 1986, I found another set.

open house for employees and their families. Displays were set up showing
items of interest, and cameras were permitted. I took advantage of this
opportunity to capture a few images to which I had not had access
previously. I am almost positive that the Kodak APS camera was my choice
that day.

for the transonic tunnel.
