Thanks for the response-i guess one doesn't notice these things from the ground without the noise alerting you to the fact that something slightly unusual is going on. i found it interesting that my wife who has a sort of interest in aircraft growing up in Cranford working for BA etc said her immediate reaction to the noise was thats not right and people who have an ear tuned from years of exposure to what aircraft sound like at different times immediately notices something out of the ordinary.
By the way going back to the orbiting process and locationwhose control would that have been under , final director or intermediate
