At least they had fewer underruns as a result of overrelying on automation. Thinking Asiana at SFO.

It should also be pointed out that if the BTV system is unhappy with anything, it automatically reverts to Autobrake Hi. Specifically there have been issues after experiencing GPS jamming. Most crew would disconnect the autobrake after a couple of seconds when it has reverted to Hi. This could account for the vicious braking, followed by the more normal braking.

Yes I can attest to that. Regular occurrence in to Incheon for example.

Thanks again all. I was thinking about why it caused such anxiety in the cabin. I think the landing was a floater which meant a late touchdown but also, from the pax point of view, an undetectable touchdown. So unless they were paying attention, the first thing that most people were aware of was a bang and things flying as the brakes came on. Had they felt the jolt of wheels on runway first, then the braking might have been less alarming.

(but impressive brakes! It would be fun to experience a late RTO!)

Double Barrel Late RTO from my Experience are not fun as SLF and I'm sure some pilots would find them anything but fun while sitting in the business end.
