They are both Royal New Zealand Air Force (RNZAF) helicopter pilots in different sections of NH90 Flight, No. 3 Squadron, at Ohakea.
The pair, with No. 3 Squadron, were deployed together for Exercise Tropic Major in Vanuatu, flying NH90 helicopters from the flight deck of HMNZS Canterbury.
They didn't meet while in the RNZAF, but through search and rescue work. Flight Lieutenant Brooke's father, a police officer in Palmerston North, coordinated search and rescue teams and knew Flight Lieutenant Stewart, who is originally from Timaru.
Knowing his daughter had an interest in joining the RNZAF, he introduced the pair in 2009. They started dating nine months later, Flight Lieutenant Brooke graduated from pilot training in 2014 and the pair got married last year.
It was inside knowledge of No. 3 Squadron's missions that helped Flight Lieutenant Stewart set up an elaborate marriage proposal. In 2015, knowing that his girlfriend would be flying past a certain ridge line in the Ruahine Ranges at a certain time, he positioned himself at the peak with a large banner saying "MARRY ME".
