frankly, it would clearly be beneficial to have this data being recorded and transmitted for the safety of millions of travellers every year, and if you or your passengers object to being recorded on the basis of personal privacy being put ahead of safety, one would suggest you find another job/airline
On the contrary it is such a huge news story with so many people interested because it happens so rarely in comparison with the number of people who travel by air. Why are you not pushing for mandatory cameras to be installed in private cars? Far more die on the roads than in the air and it would be a great way to isolate major reasons for car crashes. Why not have mandatory cameras on everyone that record in a 60min loop, could be a law that requires spectacles with inbuilt cameras? Then whenever something happens it can be instantly decided what the reason was.
When was the last time a commercial aircraft crashed and the reason for it remained unknown? I honestly don't know. Wanting these cameras is a sign of who you are, you want instant answers, hungry to know the reason something happened even though it is in no way connected to you and will probably not affect you in any way. In time I am sure we will all know why this aircraft disappeared just as we have with many other incidents that remained a mystery for some time. Relax, it will all be clear soon and we can stop with the ridiculous knee jerk reactions like suggesting live feeds should be everywhere.
