WMKC (KBR) might be just long enough to crash in but the PCN wouldn't accomodate a 777 assuming that you could land it on an unlit strip in the dark - the airport is closed after midnight (actually earlier) so no ATC, no aids except for the VOR and an aerodrome surrounded by kampung. Nice black hole approach...
WMKN (TGG) on the other hand is longer, supports a B747, is perpendicular to the coastline (KBR is inland), but also closed at this time and in the dark.

That's the new Rescue406 (has a different cap on the bottom - I've not seen one for real). The previous model in your Canadian pic and indeed on some MAS aircraft has water soluble tape holding the antenna down so in water it should release. There needs to be some electrolyte in the water - pure water will not trigger a cell reaction, neither will alcohol and the operating instructions warn against this - for this reason for land ops there is a plastic bag strapped to the ELT with salt in it so you just have to add clean water... or pi$$ in it)... but we're getting off topic.
