Eerily, today is the 20th anniversary of the Dallas thunderstorm/microburst crash.
20 years ago today, on August 2, 1985, a Delta Air Lines Lockheed L1011-385-1 crashed while attempting to land at Dallas/Ft. Worth Airport, Texas in a thunderstorm. 134 of the 163 passengers and crew aboard were killed.

I remember that. I was on a flight landing when that happened. The guy next to me in the smoking section looked out the window and said 'looks there's a storm coming and a bad one'. Ten minutes later you couldn't see two feet from the window.
