[2] In 1962, Dixon joined the Royal Rhodesian Air Force in the Federation of Rhodesia and Nyasaland and he passed his Pilot Training Course as an officer cadet.

[7] As squadron leader, he gave endorsement to a proposal from Jack Malloch to restore a Mark 22 Supermarine Spitfire to flying condition after it had been mounted on a plinth outside New Sarum Air Force Station in Salisbury.

Dixon told the tower to communicate to the commander that he was temporarily taking control of Zambian airspace on behalf of the Rhodesian Air Force.

[11] After a Kenya Airways pilot complained about who had control of the airspace (to which Lusaka had responded "I think the Rhodesians do"), Dixon said that the airport could let civilian aircraft land.

[4][15][16] He later led the bombing raid against ZIPRA in Operation Vanity over Angola flying an English Electric Canberra bomber but almost had to abort participation due to a radio fault.
