  • The strongest microburst ever recorded occurred on August 1, 1983 at Andrews Air Force Base (Maryland, USA). Peak recorded wind speed reached 240 km/h. Interestingly, Air Force One with president Reagan on board, landed at Andrews AFB only 6 minutes prior to the onset of the microburst.
  • A downburst can also capsize vessels (for example the Sea Wing on Lake Peppin between Wisconsin and Minnesota on July 13, 1890).
