I had to deal with AF1 as a line service guy after the Northridge earthquake, Clinton in the 707 at KBUR. It was much easier than I expected, The Secret Service was very thorough, but they were also polite and extremely professional, as was the crew of the airplane. I kept asking "What's that for?" while I was fueling it, the pilot simply replied that he wasn't allowed to talk about that, over and over. I finally gave up. At the end of my shift my truck was blocked in by protestors/supporters of the President and I couldn't leave which made me very angry, a simple conversation with the Secret Service guy I'd been dealing with and magically 15 minutes later it was clear sailing. The only other bad part of that day was looking up at the roofs of the surrounding hangars and seeing snipers with their scopes pointed at me, that's not a good feeling.
