Though Ferrie officially denied knowing Oswald, it is widely believed that Ferrie met Oswald far before their alleged liaison at 544 Camp Street. In 1955 both Ferrie and Oswald were members of the Louisiana Civil Air Patrol. Ferrie was asked to leave the air patrol just before Oswald joined, but apparently still remained close to the members of the organization. Though Ferrie denied any relationship with Oswald, a former schoolmate claimed that he, Oswald, and Ferrie all worked in the Civil Air Patrol. Several other members of the organization said that Oswald and Ferrie were in the Civil Air Patrol at the same time. On the day Oswald handed out pro-Castro leaflets in New Orleans, Ferrie was leading an anti-Castro demonstration a few blocks away. Guy Banister's secretary Delphine Roberts told author Anthony Summers that at least once Oswald and Ferrie went together to a Cuban exile training camp near New Orleans for rifle practice.
