twin with dark engines and dark tail

[crumb]

Flew over aughton heading southeast late afternoon. It was just out of range of my bins. It was not british as I could make out 2 letters at the start of the reg. It then proceeded to fly backwards and forwards each time getting higher for about half an hour. Possibly mapping or filming. Any suggestions guys?.

It's been in Blackpool today and took off for a flight somewhere and came back in to night stop,

Thanks--- looks like it , but from the photo, the underside of the engines are white. The whole engine of what I saw was blue like the tail.
