Interview of Roswell Incident First-Hand witness

Considering that the Roswell Incident occurred some 65 years ago, interviewing first-hand witnesses has become more difficult each year, as they become fewer and fewer each year. I have during the past 16 years interviewed several, and each one has been valuable in perhaps getting new information, or even better for me, confirming what is already known, as I have always felt verification and confirmation remain an important part of doing this research.
