Goodness, it is strange how many have passed over the past few days.
May Mr. Justman rest in peace. His work in TOS (and beyond) will be remembered fondly for a good long time. I'm happy there was a shuttle named after him--I believe he was very honored to have had that occur.
Yes, this is huge news for the Trek community and the entertainment world, Joseph Pevney and Alexander Courage this past week and now Robert Justman. He was one of the main forces that shaped Star Trek along side Gene Roddenberry.
Oh, hell, thats sad. I had just started re-reading Inside Star Trek, that he co-wrote with Herbert Solo. I noticed Justman was looking a bit frail in the newest interviews from 2004 on the TOS DVD boxsets.
