The SE missions are timed to run for 60mins.
To help keep them at 60 mins, the settings have had a minor tweak.
Anyone still up at 60mins, when the mission will end, will be counted as dead.
Lost in the bermuda triangle, albeit a just little bit over to the west of this map 
Noted Brigstock.
Keets, sorry for going a few minutes over 60 last couple of missions. Rest assured that each time all Axis aircraft were either parked or in a landing pattern at the 60 min mark.
We appreciated that flexibility which we agreed on at the start.
No problem at all changing the rules to inflexible “Dead in flight” from now on. After all, this campaign is getting seriously serious!
…and seriously good fun as well. S! to all tenacious enemies 
It’s not about flexability or inflexability. There is a valid reason to keep in within 60 mins. This is a sequential hour by hour campaign. Each mission lasting 60 mins.
I might be being anal, but taking off at 9:00 landing at 10:05 then taking off at 10:00 for the next mission is messy.
Giving a definite cut off time keeps the playing field even. Gives everyone the same time constraint.
Makes sense. Nothing wrong with anality 
Look, I don’t care whether you’re anal or not, I’m not interested (not gay or 'owt)
Noted, as the posthumous hattrick leader of the 110’s i’ll try to blow up all your stuff in 55 minutes flat, then back for medals and crumpet!
Even less, if needed, Von RichyOfen!!
