Ah yes that is true, but yeah the viewing deck isn't really good for photography. Also I went there yesterday and all the aircraft were departing and landing on runways 9L and 9R which meant all the traffic styed clear of the Heathorw Academy end of the runway which was very dissapointing.
However upon leaving and going round the perimeter road of the airport, there is a fantastic place to watch the aircraft take off from runway 9L and you get a good view of T5, just stop in at the Esso garage and you get a fantastic view of the departing aircraft as you havn't got the stupidly annoying metal sheet going across the fence which usually blocks your vision of the airfield.
Sorry Skytrain10 I thought you were talking about a viewing area I didn't know about!
