Going to jump in here with Iain's contributions (thanks Iain...) Explanations come from Iain himself:-

1-Parked at the gate, waiting for my slot time. Lots of pilots already crowding the gates of Marseille. (
Ed: That's me all the way over passed the tower, Parking W 5. Certainly didn't have to worry about anyone spawning into me...)

2-Pilots start to push back. I have to wait for my slot time, which is later.

3-Taxiing to runway 32R in heavy winds. The taxiways are crowded.

4-Blasting out from runway 32R. Bruno is next in line, Murray is up ahead. Starting the AVN departure.

5-A rather terrible washed out screenshot of the PMDG 737-800. (
Ed: I know what you're trying to do here Iain. Wait until the sun is just a little lower in the sky and it works a whole lot better.)

6-The 'string' of EHM and UKV pilots grows longer...

7-Crowded airspace around Heathrow. There were no less than six London Sectors online, along with a single approach director, two towers, ground, and delivery - and 317(ish) pilots throughout the whole event.

8-The line marches. You can see me (EHM617) behind Murray and ahead of Bruno.

9-After finding the Biggin hold full, I got swapped over to Ockham to the south-west. You can see lots of pilots on the ground at Heathrow.

10-Configuring FS2Crew, on a vector for the ILS 27L. Transferred to Director after leaving the Ockham hold.

11-Established on the ILS and over to tower. Autoland armed. Right about now I had a massive frame rate crash and it was I good thing the plane landed itself.

12-Some special traffic on the ground at Heathrow. Sorry I don't have a shot of all of us together. The airport was so busy we just squeezed in where there was space.
