The report heard that the glider was not visible on the radar system used by RAF Lakenheath controllers.
The United States Air Force criticised the glider pilot, saying: “The wisdom of operating just to the south of the extended centreline of the main instrument runway of one of the busiest fighter bases in the UK must be questioned.”
UKAB members rated it as a Category B incident, where “safety had been much reduced below the norm”.
The report also questioned how the glider pilot assessed the collision risk as low, saying it had “caused some members to wonder whether he had a particularly robust approach to the risks of fast- jets flying so close by.”
UKAB noted that the gliding competition organisers had not put out an official ‘Notice to Airmen’, known to aviators as a NOTAM warning, about unusual air activity, because they believed it was unnecessary due to all of the pilots being local.
As a result of the near miss, the British Gliding Association has now advised all its members to issue NOTAMs for gatherings of more than 20 gliders.
