Are there any remote uninhabited islands with WWII runways where a 777 could land, and no-one would know? Maybe possible alternates (unofficial) ?

The 777 is perfectly capable of landing with its communications switched off? It would be daylight by then...
The aircraft flew on for 4 hours or 7 hours? If it was traced upto 4 hours and the statellite transmission equipment was disabled/hacked to pieces by someone board, the logical course would be to turn again to an area no-one would think to look.
