High circuits at LHR

[HZ123]

At weekends there appears to be an Islander or similar circling hour after hour around LHR and I would guess about 15000'. Is this surveying or anti-terrorist patrol and if so whose a/c is it.

I don't see you getting any substantive or useful reply to your question.

Therefore you are entirely free to come to your own conclusion.

I did indeed get a response that they were in all probability MOD surviellance flights that also appear to take place over Portsmouth. Rgds.

I saw it about a month ago over LHR.

Hmmmmm......at 15000 feet you say in an Islander.

Wonder how long they can hold their breath?

:rolleyes:
