So you're saying the people I often escort on a tour of the tower are imposters????
Hard....but fair
I used to enjoy tower visits when I was on shorthaul airport standby. An excellent way to pass the time, meet the peeps in the fish tank and learn more about the LHR operations (and LGW too). I haven't yet been to your new tower but will once you've got it all properly built and take away those bit of string holding it up
As for BA heavies rolling long, you'll probably find it happens as much as poss on both the 09s (once the work at the 27R threshold is completed of course). Parking on the Deltas for T1 or, T4 from both runways, means a bit less phaffing and getting lost during daylight hours by staying on the runway and avoiding the taxiways
Of course, come T5, in addition to the end of world poverty, cancer, terrorist attacks and everything else that will be cured by the opening of it, I think you'll see a lot more long rollouts on the westerlies (don't know about 27 North though)
Okay, I'll leave you chaps in peace again and concentrate on my alter-ego as a millionaire sex god
