It is really annoying to me as I live so close to Gatwick and used to use the Skyview loads at the weekends.
It really annoys me more that BAA do bu**er all to find a replacement to skyview and this means all the enthusiasts have to be chased by police if they go near the perimeter fences for a few photos
The prime location for a new terrace would be on the office block roof of South Terminal. From there you can see 26L and possibly the full runway depending on how wide they make the terrace.
It would ultimately have to be on terminal roof (North or South) but would be good to have two viewing terraces one on South Terminal Office Block Roof and then one from North Terminal roof. Both locations would give great views. Would be minimal cost to BAA they just can't be
