Dekkers purchased
Huffman Aviation in 1999. At the time of purchase, the school had a fleet of 12 small aircraft. Atta and al-Shehhi had attended the school to learn how to fly small aircraft. The two first trained at Huffman in July 2000 after they first met with Dekkers while he was on a coffee break in his office at the school. In August, the school filed the M-1 student visa request forms for Atta and al-Shehhi to switch from tourist
visas, to student visas, in order to allow them to enroll in the school's professional pilot program that would last from September 1, 2000, until September 1 the next year. The student visa requests were granted on July 17, 2001, for Atta, and August 9, 2001, for al-Shehhi. For a short while, during their time at the school, both Marwan and Atta lived with a company employee named Charlie Voss. Following the attacks, media reports and the investigation into the attacks led the
FBI to Huffman Aviation. The FBI seized records from the flight school which revealed that both Atta and al-Shehhi paid $10,000 for two months of flight instruction. Dekkers cooperated with the FBI from the start with former FBI investigator Kerry Myers who said that "Rudi was very cooperative. He didn't require a subpoena, he didn't require a court order. He was a good American citizen." Meyers stated that evidence linking
Ramzi bin al-Shibh, described as one of the people to be the possible
20th hijacker, to the attacks came from Dekkers' cooperation and records found from both hijackers. Dekkers also maintained that he did not feel guilty and he had made copies of their passports and their visas, but he said there were no red flags asserting "Nothing was out of the ordinary. We did our job." After the attacks, Dekkers went bankrupt, lost his business and house, crashed a helicopter, and got divorced, losing custody of his daughters. Since media attention focused on him, Dekkers enjoyed his time in the spotlight saying "The camera loves me." He had been criticized for his alleged lack of oversight at the school. He countered back with the United States' lax national border security and visa systems which would be confirmed when he found two approved visa applications from the U.S. Immigration and Naturalization Service for Atta and al-Shehhi in March 2002. After the attacks, he wound up losing four hundred thousand dollars, and most of his students who were primarily international later dropped out. A second school he operated in
Naples, Florida, was closed after he was sued by a former business partner after defaulting on a series of loans, one of which accounted for $1.7 million. Dekkers sold Huffman Aviation in 2003. Dekkers stated in 2011 that the two men "never displayed any behaviors that would have labeled them as terrorists." And at one point during their training, "the two men were on the verge of being kicked out of the school because they did not appear to be taking their training seriously and were too busy fooling around and not listening to their instructors. They had to be warned, and went on to become average students." He would get along with al-Shehhi describing him as "a more likable person. He laughed and joked." However, Dekkers and his employees described Atta as "dead man walking" due to his "white face and no emotions and was a nasty person, very unfriendly". Dekkers stated that he did not know what they were going to do and maintained his innocence, "I don't feel guilty at all. I couldn't do nothing about it. I wish I could be a hero. I think about this often. Why me? But that's fate. You can't turn away from fate, I guess." Dekkers stated in 2016 that his personal "9/11" began on September 12, when the FBI appeared at his business. "For me, it's not an anniversary. I live 9/11 every day". ==Later life and death==
