The crew clearly is not fully trimmed, some of the crew even seem a bit confused abour their task... There is no way of telling the actual time this took because of the numerous cuts in the video, but a full arming and refueling would take less than about 12 minutes. We rarely did full rearming though. My crew ( my initial job was to load the cannon and later in my service, to lead the munitions crew) did quite a few turn around displys and got a lot of practise :)
A typical display rearm/refuel cycle (80% fuel, 2 rb74, 2 rb71 and 125 30mm cannon rounds) usually was about 5,5- 6 mins with a well trimmed crew. The 80% fuel limit was due to restriction issues with the following air display.
