Great shots! The viewing area at BHX gives many chances to photograph aircraft. Where Grey area took his shots were at the picnic area but if you have a small enouch camera lens, it will fit through the gaps in the fence. If not, a pair of step ladders are required.
Another place is in the long stay car park ajacent to Rwy 33 which allows good head on or side shots of aircraft. Again, a pair of step ladders are needed
