RAF Cosford, England - (EGWC)

While this is still an active Royal Air Force base, there are really no aircraft based here except the volunteer glider squadron, an EMS helicopter, and a flying club.  However, there is a museum that rivals most any other within its boundaries.  Located just off the M54 motorway about 15 miles northwest of Birmingham in the Midlands, it is worth any and every side road used to get there!  There are no fewer than 50 unique aircraft presented within its hangars.

Gloucestershire, England - (EGBJ/GLO)

This small airport is just off the M5 motorway about 30 miles north of Bristol.  Manx2 is the only commercial service as of now operating 2x daily with a Dornier 228 to the Isle of Man. (Equipment sub the day I was there to a Let-410)  Most of the hangars and ramp areas are located on the SE side of the airfield making it a morning or early afternoon shooting affair.  Always worth a stop if you're like me and don't live closer than 3,000 miles away.

Normally a shot I wouldn't take but the pilot would not get out of the way!

Blackbushe, England - (EGLK/BBS)

This general aviation airport is situated a short ways from Farnborough, just north across the M3 motorway. (about 10 minutes driving time)  Of course, as every airport is worth a look I made the trek.  Situated right next to the knee level fence were 2 Cessna Citations as well as many smaller GA aircraft.  As the aerodrome is just off the road, it would always be worth a stop just to take a peek.

London/Luton, England - (EGGW/LTN)

One of London's many airports, Luton caters mostly to the spotters who are looking for "monster biz frames" as this airport attracts business jets from all over the world on a daily basis.  It still is a commercial airport but you are relegated to discount carriers EasyJet, Wizzair, and Ryanair.  Monarch and Thompson have a maintenance facility here so you never know what types will be in for them.  Again, as with most airports in the U.K. this airport's spotting locations are well known and can be located on the internet with ease:   http://www.spotterswiki.com/index.php?title=London_Luton_Airport

The day I showed up, they were operating off runway 08 which made for some great shots taken from the crash gate on the south side of the airport.  Due to the close proximity to the runway you can expect to get even the smallest mustang-like jet with a lens no bigger than a 300mm, with most subjects being a short 125mm-200mm away.

First Choice 767-300

I had the opportunity to visit this great airport whilst on business and the weather even cooperated.  Being a UK airport and spotting being such a huge hobby over here, this airport has been covered in depth.  I found this information to be quite helpful in my search for spotting areas:

http://www.spotterswiki.com/index.php?title=Manchester_Airport

The following were taken from the hill as described on that site as "South Side runway 2".  They were only using runway 5L the day I visited which requires a fairly sizable lens. (at least 200mm for A380 and 300mm for narrow bodies)

Jet2 737-300 G-CELI landing 5L

KLM retro scheme 737-800 PH-BXA arriving 5L

While I was standing in the same location, the runway was switched from 5L to 23R.  When this happens it effectively cuts down the amount of shots you can get as you are quite a ways down toward the departure end of 23R.  Only heavies roll long on landing as evidenced by the following Qatar shot and most narrow bodies are quite high by the time they pass you.  The only real good opportunities are when the heavies depart as they have a longer takeoff roll.

The sun is brilliant for most of the day from this location.  It will depend on the time of year as to how much sun you get per day. EGCC sits at a latitude that makes for short days in the winter and much longer ones in the summer.  I visited in January and wasn't able to start shooting until about 0900 and the sun started making long shadows around 1300.  At that point you can pop over to the other side of the runway at park at the official Airport Viewing Area at a cost of 3 Pounds per hour (quite steep) and try your luck as the aircraft vacate the runway or taxi by you on the way for departure.  All the aircraft actually on the runway are still somewhat backlit as evidenced by the Air France A320 shot below as an example of the poor light.

Overall this airport has probably the best vantage points of any airport in the UK with a good amount of traffic as well.  And because the spotting hobby is so big over here, you can be pretty much be anywhere outside the perimeter fence and the police just drive by, smile, and wave.  Not being hassled over and over makes for quite a pleasant and enjoyable day.
