On May 5, Hazmi and Mihdhar took a lesson for one hour, and additional lessons on May 10 at the Sorbi Flying Club, with Hazmi flying an aircraft for 30 minutes.[1] However, their English skills were very poor, and they did not do well with flight lessons.[2] The first day that they showed up, they told instructors that they wanted to learn how to fly Boeings.[21] Mihdhar and Hazmi raised some suspicion when they offered extra money to their flight instructor, Richard Garza, if he would train them to fly jets. Suspicious of the two men, Garza refused the offer but did not report them to authorities.[19] Garza described the two men as "impatient students" who "wanted to learn to fly jets, specifically Boeings."[22]
