quoted from OP
''I believe the distinct possibility is that MH370 may have suffered a Lithium battery fire and explosion in the forward cargo hold damaging the adjacent avionics and communications compartment which would explain the loss or the Transponder and ACARS system. The onboard fire or explosion then penetrated the aircrafts skin causing a rapid decompression of the aircrafts hull.''
that sort of fire would have brought the 777 down PDQ and if your theory is based on the above how do you know where and what hold the batteries were loaded in?
do you have that loading info?
would a hypoxic crew have made several controlled turns and also turned off the transponder?
in response to another post it was the Capt's home PC flight sim program that had this routing on it
not the FO
