R-R - no, you are spot on, but don't follow your point about the masterplan being a wake up call?
Meanwhile...
the only mention has been of a duty officer and security staff overnight (presumably additional security staff?) - no mention of extended opening hours. Presumably even medevac and transplant flights are AOC so would need ATC at least?
Off topic, but note that a NCL apron G could be used for overnight parking, so 4 stands there and I believe the main apron is still not back to the peak years for ONS.
