Out walking the dog about 5.30 in Potton, Beds when I heard a heavy helicopter flying overhead - initially I was unable to see it and it didn't show up on Flight Radar - but when it came into view I estimate that it was about 1000 ft and flying slowly compared with the R22's and the Chinnooks we see regularly. From the large sponsons and the single horizontal rear wing on the port side I think it was a CH53 but instead of the usual military green or grey it was white and appeared to have civilian markings.
Are there any civilian CH53's in the UK or was it in arctic colouring?
