As short courser last year before they moved there was even more congestion, but this is where you learn airmanship folks when VFR. The controllers do their best but have lost some excellent experienced people last year. I did my PPL at Biggin, 9 in the circuit average, Bizjets and 7 Flying schools, two helicopter schools et al. You learn what lookout is all about, immediates, RT on the ball,positioning for correct and safe spacing yet keeping the traffic moving quickly and efficiently and the controllers there with their archaic systems do a fabulous job.
Oxford ATC need our support and some continuity with staff not censure as we don't know the facts.
So glad no-one was hurt this time.
