Apologies if this has been mentioned before ( in this case I have to admit to not having read the entire thread ! ).... It would appear that BA and their legal advisers have been somewhat remiss in not bringing forward medical testimony relating to memory retention...there must be volumes of studies involving the brains' ability/inability to absorb and retain complex data over short and long periods.... The tribunal themselves must surely have been aware that any successful barrister would be able to demonstrate the ability to study over a short period extremely complex evidence and succesfully cross-examine an expert witness on their own subject...only to forget 80% of what they learned within a month....
The need for long exposure to new complex data for it to be retained over a long period is evident in many disciplines and surely must have been studied in depth over the past hundred years.... This need would appear to support BA's policy of flying for a prescribed concentrated period...
