The " emergencies " were due to thunderstorms over Madrid forced three separate FR flights to divert to their official alternative airports, known as 'Alternates'.  In this case all three had VLC Valencia as their alternate.  What happened then is open to conjecture but it could be considered that the approach controller at VLC decided that these three unwelcomed intrusions into his orderly day were, well, unwelcomed.  So he sent them off into a very wide orbit, round and round and round, while all the regular business landed and took off as normal.

What happened next?   Well after some time - the aircraft always expects ground control to give it advice and instruction - it does NOT ask for a progress report - after hearing nothing for some while, one then two then three in short order all start shouting they're running low on the sector fuel ( remember they have already burnt their diversion fuel) and the flight deck crews start wanting some attention please...PLEASE... like now !  please.  Suddenly the approach controller realised he/she had overstepped themselves and authorised an urgent approach and let down.  Fire crews would automatically have been scrambled....like, all of them... blues and twos...the hospitals would have received notification of an possible incident; civil emergency services' stand by would be upgraded. 

The prat was the approach controller.  Hopefully he was taken off watch for 'training'.

Ryanair (FR) as a company was in no way responsible for the incident and at no time were any passengers at risk. The safety margins in modern civil aviation are almost beyond comprehension; never, ever doubt the competence of the people up front. 

Always, gentle reader, always listen to the announcements and make bloody sure you know, when IT happens,  how to get out when the 20 year old cabin attendant has fainted.  I have absolutely no faith in FR cabin staff.  It's Easyjet for me every time, but then I know their training regime.
