An Off Duty Captain flying in back reported seeing a "Fuel Stream" exiting the wing on the Tail Camera feed to his seat. Torn Skin was visible on the Wing's upper surface. The engine's casing was in plain sight. The Casing's shredded state I assume to have been visible. There is a downside to over sampling, especially when it is Human eyes doing the sampling. This could literally have gone either way, and I doubt that the unfolding of events as it happened here, would be trained to the future.
Hindsight is keen, as above, but fraught with opinions that may indicate ways to deal with an unknown that are futile. Uncontained Bursting is not planned for, any provision for its occurrence steps rapidly into the unknown. It is such a potentially lethal situation that it cannot be assessed from a Risk/Benefit position.
Hindsight/Opinion, IMO
On second thought, A barrier against catastrophe is in the cockpit already. A savvy and Experienced Flightcrew. Kudos.
