If I remember rightly, there were many thunderstorms floating round Europe last year, which caused a lot of delays. As for the runway being repeatedly closed... not sure how you mustered that one up and Omniserve manage the PRMs, not MAG.
Thunderstorms are a standard part of summer effecting departures from all airports, not just STN. I mustered the little gem about the runway closure due to holes from the fact that I had to divert twice last summer and again just a few days ago. The runway is falling apart. Omniserve (fail to) manage the PRM service as a monopoly at the behest of MAG. MAG are responsible for the management of their airport and their service providers.
