Thanks for the input guys.. appreciated.. 2 months plus would appear to be an excessive period of time to check out the five ILS's currently functioning here in Afghanland and as for anything secret, that's very unlikely .. that's what we do and it's not that simple.. In light of what's been written here it's possible that it might be assisting with calibration of the new radar installed at Mes over the last couple of months... If I was a cynic.. which I am..I'd suspect that they're dragging it out so as to spend more time chatting up the stunningly pretty German lady in the tower.
