MillCreek, Bob,
Pectoral muscles are best developed during alternate gear extension drills using the bold face.
61-2667 is the last of the WC-135 fleet still flying as a WC-135. 666 is the Raytheon test bird in Greenville, 670 and 672 are Open Skies OC-135's, the rest succumbed to corrosion or budget cuts.
I spend a couple days at Davis-Monthan earlier this year, doing the airshow thing and looking for spare parts. Here's WC-135B tail number 673:
Sad, but here's one that really grabbed my heartstrings, WC-135B tail number 665, now just a tube (maybe I can buy her as an oversized Airstream trailer and live in her during my retirement?):
We did luck out, though. With the nuclear reconnaissance fleet shrinking, Air Staff authorized us to take former Looking Glass EC-135C 62-3582 and convert her to a WC-135C. It freaks out people when they see it, because it still appears to be a Cold War Looking Glass. But she's all new inside, and new paint outside. The boom's still operational, as are the extra HF antennae. Here she is at Patrick AFB, my wife took the pic on November 3rd, chocks in place, fire hose about to be aimed at me as I step down the crew entry ladder for the last time. Note the new equipment mounted on the fuselage above the wings:
