Just what exactly happened here?
Gulfstream IV N842PA on 23 May 2017, BHX to Wilmington.
Found out afterwards this is reputedly the flight taking Ariana Grande home early from her ill-fated tour of the UK.
Update – confirmation of the reason for the flight is at http://www.wwaytv3.com/2017/05/24/ariana-grande-makes-brief-stop-at-wilmington-international-airport/
