Hi Air Hop
As far as I know, there was a sub aircraft in EXT for the D4s, probably a Titan as it positioned in from STN. We are hoping to have everything reasonably back on track on Tuesday so I don't expect that there will be any additional subs in at EXT.
The line up was nice and I only wish I had my camera on me at the time.
I do hope that the TS flight doesn't arrive at 06:00 because I will not see it before I start work....at least at the moment I see it during my lunch break! Would be interesting though as you say because the 1st departure is at 06:30 and the apron is reasonably busy at that time.
TS would be better putting it forward a couple of hours. At the moment the Wednesday morning has a GSM B757 and an Onur Air A321 plus any BEs that may have a small delay at about 08:30
