Chill
Also in support of WMKN there was a post a few pages back regarding people on/close to Murang beach hearing strange bang/turbine noises which coincides with the timings of the lost aircraft. On pulling out a map WMKN it sits jutting out as you said perpendicular to the coast just to the north of these reports, it would be a very reasonable diversion airport to aim for in the event of any major failures. (As long as it's not closed of course, I'm unfamiliar with the region). However being that close in towards land/people I would suspect evidence of the aircraft would have been more visible to find.
