Charles was on the Airline list back in the mid 1990's and joined a lot of us in moving to Skyone when we became fed up with the moderator of the Airline list. He is an independent contractor specializing in DEC VAX/VMS system administration.
For a number of years around the turn of the millennium Charles had a very lucrative gig as an independent contractor working for United Airlines at their main maintenance base at San Francisco International Airport. He commuted weekly from Aventura on Delta Air Lines from FLL to SFO and back. He was the only person administering United's aircraft maintenance base VMS computer systems. After 9/11, United suffered huge losses and Charles lost his lucrative gig at SFO.
