Ryanair $10 sale for travel in Europe

Ryanair is having their occasional-not-quite-annual 10-euro/10-pound flight sale! The website keeps going down and the prices keep disappearing as they are snatched up, but this is still too good to pass up. I just snagged a flight from London Stansted to Berlin for $16. Check out the fare finder at Ryanair.com. If the Ryanair site is glitching out, try google.com/flights instead to check particular places and dates.
