Lets see now, we've had 'The Trench', for WW1 infantry, 'Spitfire Ace' for WW2 fighter pilot's, then there was the series thats just finished about D-Day infantry training, before that, we enjoyed a Dambuster Crew re-creation and now we are promised a Bomber Pilot series.
It seems to me that someone has just noticed a gravy train and is intent on hitching as many carriages to it as possible.
I enjoyed watching all those programmes, but if TV follows its normal path, there will be a surfeit of this sort of viewing as each channel trips over itself in a vain attempt to copy the opposition.
