I'll second BBF's comments. LCY ATC and Thames do a great job and give a high quality service to all in a very stressful and busy piece of airspace. The regular postion reports on VFR traffic is very informative and helps with SA.
And credit to the rotary drivers who excercise such discipline in such an enviroment and always excercise the upmost proffesionalism in assisting ATC and the departing/arriving traffic with separation.
