Quote from ISCA
As an aside to those speculating the aircraft could have been "secretly" fully fueled you obviously don't know much about refueling procedure.
Well it appears unfortunately you do not either.
Different Airlines bestow different levels of responsibility and authority in allowing their crews to upload whatever fuel they feel is justifiable.
Therefore, unless you know exactly what MH crew refuelling policy and procedures are, the view you are espousing carries no weight.
Their fuel load was I believe still an area of discussion.
