Les, I knew of at least one of these incidents but not because of my military service. The C-130 shot down over Armenia has a Gerald Medeiros listed in the middle column of the PDF link you provided.
I've known his brother for nearly 25 years and worked with him for over ten! We spoke of the incident on several occasions. His brothers (Gerald) remains were mixed up with another crew members remains and buried in Louisiana. Due to some research, dumb luck and a persuasive family, DNA evidence was able to prove who he was and his remains were interred at Arlington in about 1998 or 1999 with full Honors! His mother was able to attend and finally get some closure after years of Government ineptness.
Thanks for service as well. It truly is a small world sometimes...
