Null,
I seem to recall brake seal problems on the 'K' when going from hot Changi to freezing Kimpo. I have a recollection of hot air blowers being applied to said brakes. We used to take the Honour Guard up for changeover in Korea. I wonder if smudge arrived on the fleet before the wing mods made 'open line' refuelling impossible. We could not have gone to many of the small islands we did go to without the capability to overwing refuel. BGE (before Ground Eng) I have often helped the Air Eng to refuel over wing. And to operate the pump for the FSII additive.
The only open line refuelling after that was to fill the internal tanks on the tanker
