I thought this discussion (and hence my earlier comment) was about the intermittent nature of the new Farnborough LARS services North and East of London. In our neck of the woods, we don't have much low-level jet traffic but we do have the occasional helicopter at 800' where Farnborough probably can't see them!
Don't worry chaps, I always keep my eyes wide open, especially around the south-west of London!
I flew Compton Abbas to Fairoaks and Biggin the other day and Farnborough West were very busy due to a heck of lot of light aircraft, gliders and microlights around West and SW London. I can imagine getting a Citation through that lot might have been
interesting!
