Looks like they tried two attempts to land in Prestwick over two hours, then flew to Edinburgh and made one aborted landing, then finally went to Manchester. What a nerve wracking experience for those pilots. I wonder if on the final attempt they knew they had to force it down no matter what.
Context: because of bad weather. But I'm truly surprised (in a bad way) people on the ground couldn't solve the situation earlier. The plane was in an emergency situation for hours , wtf. Also, the airport density in the UK is high, they should have been diverted since before the first attempt, as it has happened to me and thousands of flights every single day around the world.
Edit: there might also be part of Ryanair culture that contributed, but that's speculation.
