The whole of MANs perimeter is getting upgraded to DoTs security specifications which includes higher, stronger fencing.
One of the major attractions of the viewing park is the ability to stand on the mounds and look over the fence. Obviously the old mounds won't be high enough, fortunately the viewing park management have realised this and as a result they are spending a considerable amount of money to make the mounds bigger.
No not a waste of money, an investment in a facility.
How many other airports in UK would go to these troubles ?
