Rudi Dekkers (July 27, 1956 – April 11, 2024) was a Dutch businessman and convicted drug trafficker. The former owner of Huffman Aviation (a flight school in Venice, Florida), he became the subject of worldwide attention after the September 11 attacks when it was revealed Dekkers had trained two of the hijackers—Mohamed Atta and Marwan al-Shehhi—who crashed American Airlines Flight 11 and United Airlines Flight 175, respectively, into the Twin Towers of the World Trade Center.
