"Ninety-three is quite old. I wasn't sure of his ability and whether he would even have the mobility to get into the aircraft."
"But he flew very well. For 93 he is incredibly agile and flies aircraft to a high standard."
Mike Richards from the Civil Aviation Authority said Cox was one of the three oldest pilots still flying in New Zealand, but not the oldest. There was only a year between the three.
"It is an incredible achievement and testament to a safe flying history for a pilot to continue to be in the air in their 90s."
Cox - who has more than 21,000 hours' flying experience meticulously recorded across 12 log books - also had to sit a medical assessment equivalent to that needed to drive a truck, and pass an aviation law exam to get his licence.
He said it was hard to describe "the feeling of being on your own in an aircraft".
"It was very satisfying to feel capable and in control. It brought back memories."
Cox has joined Tauranga Aero Club and said he planned to fly once a month or so to keep his skills sharp.
He would mostly do circuits and practise different landings, but had a couple of friends who were keen for him to take them up to see the sights.
Asked what his family thought of his renewed interest in flying, he said they were "a bit reticent".
"None of them [his four children] have asked me to take them up."
Cox began his flying career when he enlisted in the Royal New Zealand Air Force in May of 1943, aged 18.
"I didn't like the idea of someone sticking a bayonet in me in the army or drowning in the navy. A fighter pilot has the most control over his own destiny, that's why I chose the Air Force."
He was a fighter pilot for four years and has written three books about his experiences. He is the only living survivor of Black Monday, RNZAF's worst single-day loss of life.
After a nine-year break from flying, he became certified as a flight instructor, opening Manukau Flying School in 1966. At the same time, he did charter and other flights before retiring from flying in 1993.
