Also in 1985...the crash of a Delta Air Lines L-1011 in Dallas that killed 137.
There's always been a lot of speculation over how IBM gave up an entire industry (the personal computer) to a seemingly insignificant start-up (Microsoft). One theory is that may not have happened if Don Estridge hadn't been killed in that crash. More about him here:

Of particular note:
"His most revolutionary move was to make the computer's design specifications public, allowing thousands of young people to write programs for the machine."
We take it for granted now, but before Don Estridge and the IBM PC, "proprietary" was the rule and "open" was the exception. RIP
