I think we're all getting carried away here. The metar produced by Goforfun states broken CB at 5,000'. That's fifteen miles finals, chances are the Ryanair flew around it and made his approach well under it. A4 says he was there on the day, but not when. Thunderstorms tend to move around. My guess, and I stress it is a guess, is that the Ryanair quite correctly avoided the worst of the cells and made a perfectly normal approach and landing. He took a strike at some point, but that could have been in a very minor cell, or even some way from one. Let's leave the Ryan-bashing for when it really matters.
