The Republic of Singapore Air Force (RSAF) has released a video that provides a glimpse into how the photos of its aerobatics team, the Black Knights, and their manoeuvres for the country's recent Golden Jubilee celebrations were taken.
The 1min 21sec video reveals that the RSAF worked with renowned Japanese military aviation photographer Katsuhiko Tokunaga for the photoshoots.
He can be seen choreographing the planes' movements, and also speaks about how he signals to the pilots to get smoke trails.
According to the video, Mr Tokunaga's favourite manoeuvre of the Black Knights' is the Dedication Pass, in which four of them would fly in a diamond formation while the solos would spiral around their smoke trails.
It was a routine specially conceptualised for Singapore's 50th birthday celebrations.
As for his thoughts on the Black Knights, Mr Tokunaga says in the video that the cooperation level, from the commanders to maintenance and administration personnel, is very high.
"It was a very nice experience to work with them," he said.
