one thing seems a little strange to me .. the Captain on the radio to ATC..he seems to be having some kind of trouble with virtually all the read backs ..lots of aa..ahh ..err.. ehhh..malaysia ONE ...7370 ... etc
small things maybe and yes its the middle of the night and he had flown a lot of hours in the previous 28/90 days..
the only read back without any prefix of err ahh aa etc is the very last one .
very precise ( although with no new frequency mentioned)
probably means nothing at all ,just made me think a bit .
