How can two aircraft collide considering all the 'in built' safety contained within two brand new airframes? Add to the equation, within extremely 'quite' airspace compared to Europe and North America?
If this was a freak chain of events culminating in such carnage, those involved were shockingly unlucky.
For whatever reason, TCAS/ACAS has not prevented a mid air collision, why? A question no doubt on the lips of many folk?
A glancing blow over millions of square miles that is just jungle.
