1. ITV reporting is definately tabloid compared to BBC's more restrained broadsheet version.
2. The photo at #146 appears to show a black 'paint scraper like object' piercing the green inner hull along a vertical seam about 3 panels below the bottom of the hole. Could this have been pushed through by weight shifting above (early bang), causing a slow puncture until an aerosol of hair spray etc in a soft bag on top against the hull 'exploded' causing the main damage (top of hole)
I note the luggage was not containerised, just netted and appears to plug most of the hole
Is the forward cargo hold pressurised?
The a/c was about 1 hour out of HK cruising at FL290
Just conjecture but we tend to forget aerosols can explode like hand grenades in low pressure environment, not just bonfires!
Finally, respect to all crew & pax aboard. I bet even the Captain went a little pale when he finally saw the damage.
