I was flying first class on a TWA L-1011 flight from SFO to BOS in 1983 carrying a Radio Shack M-100, one of the very first laptop computers. As I took it out of the case and placed it on my tray, the woman sitting next to me (who turned out to be the manager of TWA's Boston Admiral's Lounge) was very curious about it, and so I turned it on to show it to her. Just as I flipped the switch, the plane started to bank, and I experienced a momentary fright that perhaps I had caused this to happen by turning on my laptop. Turned out I didn't, but perhaps this was an omen of things to come.
