I know about brake cooling thanks! I've lost 4 tyres at LHR on a high speed abort.
Before the famous Pprune Court Martial convicts these guys, let's remember they appear to be able to run a regular operation without appearing in the news with overheated brakes everywhere. I'm not sure what the loads Budapest-Athens are like, but they were probably quite light, and returning on that leg, there is plenty of time for brake cooling. 3 Autobrake/Idle reverse is quite a common selection for landing- I use it myself many times. Power above idle is not always encouraged for wear and noise reasons.
So let's, people, enjoy the video for what it was- a very generous opportunity to allow videoing on the flight deck (which they shouldn't have allowed) and not use every available possibility (and manufacture some) to attempt to find criticism!
