When I saw the attached picture my jaw literally dropped, I have never seen a tail strike that bad before! (Even the serious Emirates incident at MEL a few years back looks nothing but a mere scratch compared to this)
For the crew to report a ‘loss of pressure’ this would suggest they went above 10,000 feet? Which would also suggest they originally had no intention to return to the airport and had planned to continue regardless? If that’s the case, this was sheer recklessness from the crew; whilst it’s not uncommon for crews to only realise they’ve had a run-in with the tarmac on post-flight inspections at the arrival airport, I find it hard to believe that is the case here.
As MSR777 mentions, this could have been a lot worse.
