So as a member of the ULD sucking profession is it your expert opinion, based on your ULD sucking experience and a grainy video, that the engine is destroyed?
As an engineer, not even one with engines as a speciality, I'd want all the front fan blades checked for minute fractures, as well as the disc, plus a really good check of the rest of the blades for impact signs and a really good check on anything else with impact damage. Most of it will likely be intact, but the check and repair cost may well be rather large.

I might not be an engine expert, but I've read up and seen what can happen starting with the tiniest of cracks. If you're lucky you'll just have a blade come off, and it'll all stay in the casing. If you're unlucky, the disc will fracture and it's pot luck on which direction the high-energy debris will exit the side of the engine.

Then I'd let someone else be the first to run it up, both for the ground test and its first flight.
