Fantastic visit to to Heathrow tower on Sat. many thanks to all involved in origanising it. No Gonzo, you weren't at all boring!
I'd recommend this to anyone who flys, and to people that don't for that matter, it really is very educational.
And can you have a better view out of the office window than Heathrow's runnways either side - except maybe from the pointy end of a 747!
Thanks again.
