Having worked as a contractor at both sites, the quality of engineers was without a shadow of a doubt the biggest asset ATC had, however the management was stuck in the 70's... Ultimately lack of investment in their infrastructure & treating their staff poorly came home to roost, I have rarely seen such a discord between management & the workers. Sadly everyone suffers when an organisation like ATC goes, it served me well for progressing my career, & I can only thank the people I worked with & wish them well for the future.
