I recently met Phil Chouinard of Hudson NH. Phil was part of the NAR S&T team with Bill many years ago and knew Bill. Phil has also done a lot of work with the McAuliffe-Sheppard Discovery Center in NH. He was diagnosed with Alzheimers a few months ago and is no longer involved with rocketry. He has donated most of his collection, including his educational materials, to CMASS and will be included in the next Bill Spadafora Memorial Auction (more in April - so stay tuned!) Included in that are a couple of posters for CMASS and a CMASS flyer from long ago!
I'll bring them to the next launch.
