I was the one who sent the bird around. A combination of events led to the olympic being unable to vacate at his chosen turn Blk 85. The pilot tried his best to make 86 in time however with the poor weather and the speed of concorde on the approach the go-around became inevitable.
Sounded and looked good from the tower.
If anyone knows the pilots of the conc on saturday put them in touch as i owe them a beer!
