Yes, to the best of my knowledge it was Balfour Beatty who imposed the
'Development' Fee.
It was Balfour Beatty TSR2 for certain. The airport was buzzing until FR left.
What gets me it was an outbound tax only - With free car parking was the ADF any use at all?
Balfour Beatty seems to have gone out of their way to alienate FR and later LS - makes one wonder why.
