Lucky it wasn't QANTAS, there would have been a full investigation by now and somehow the engineers would have got the blame.
It's so similar in Australia, we can have multiple turn backs due to hydraulics, pressurisation etc. but if it’s not QANTAS it doesn't make the news!
Time to move on or do we have to wait until the next return to catch the attention.
BTW not a Ryanair lover, just know that stuff like this is not unusual, I have seen much worse.
