It sounds great. It sounds like RETWA was bothering with animal welfare like never before (and likely never again).
But really, what were these experts actually doing? The captain should have been quite capable of monitoring weather conditions - that's a key part of the job. The onboard veterinarian should have been quite capable of detecting heat stress in sheep - one hopes that is a key part of their job.
And what were the panel of experts actually going to do when conditions inevitably got hot? Blow kisses from back here in Australia in the hope it would cool the sheep down?
