OOps. Think I must have had a bad day when I made 'that' post!
My sincere apologies if I offended, really wasn't intended. Just curious to know how NERC was going for real and suppose could not see the relevance of London Weighting which I (perhaps stupidly) assumed any NATS employee would know about re NERC - no they don't get it - or Home to Duty Mileage allowance.
Again sincere apologies, will be more careful in future when wording replies. <img src="frown.gif" border="0"> <img src="frown.gif" border="0"> <img src="frown.gif" border="0">
