UAL 922 (763, EWR-LHR) diverts to Santa Maria Island (LPAZ / SMA)!
Surprised this hasn't made it here yet... sounds like a pretty unusual diversion:
UA922 - Flights list - Flightradar24
Consolidated "Delayed/Cancelled" International Flights (2015) - Page 166 - FlyerTalk Forums
This looks like a very "large" diversion... nowhere near original track (?)
Aircraft has been retrieved and (presumably) ferried back to EWR...
