Hi Captain Flynn.. Could be. Here's what I wrote some years ago about it:
UK registered passenger jet in, or close to, the Ockham holding area. The crew reported seeing an orange disk shaped object pass close to their aircraft. Nothing was seen on radar. When the aircraft landed the Captain contacted ATC and it was decided that the best way to get the matter properly investigated was to file it as an airmiss rather than as a UFO report. I believe the resulting thorough investigation to have been inconclusive.
Sorry I can't be more specific with details..
