Truth or convenience?
One thing I noticed on the Govt's website was that the basic content of the submissions could almost be predicted based on the position of the submitter.
For example, the airlines and any organisation which might have a vested interest in having this issue remain unrecognised say something along the lines of 'there's no problem' or 'nothing's been proven'.
Conversely, those who have had their health and livelihoods messed up are saying 'there most certainly is a problem'.
Can't both be right.
Looks to me like one group want commercial interests prioritised, and the other want the truth.
Draw your own conclusions.
