the pilots know this. this is the current look of a private briefing. can you see ahs yala down to the south. on the edge of your screen you can see ahead and up towards singapore. it is in this area of red. this is occasional embedded thunderstorms at 53,000 feet high. in between the thunderstorms, there's down drafts. it's reasonable to assume at this point, martin taking off this first thunderstorm, at tremendous height possibly 53,000 feet maybe 55 as some reports are saying could have caused him to divert this area because this is the anvil right in front. then you get into a clear pocket where possibly we call them cold spots. we're in the down drafts occurring. then he is embedded and this is the last place of known contact.
