I don't know the thrust profile of the 787s engines but that's, like, an afterburner or rocket amount of thrust if it's true. I'm not sure a pilot could command the plan to do what it did, but she's a fly by wire bird, so it seems consistent with the pilots story of the flight computers on the flight deck all going black scren and seemingly resetting during flight and causing chaos
Crazy story, thanks for posting an actual news update

“There wasn’t a lot of explanation on what did happen. Suddenly we were finishing lunch (then it happened),” Mr Ellwood said on Tuesday.
“There was wine on the roof and there were people on the roof. It was just a scary, terrifying moment.”
Mr Ellwood said he was holding his iPad and filling out a passenger declaration for New Zealand when the incident occurred.
“The declaration form and my iPad both hit the roof and came crashing down immediately. It was crazy,” he said.
