Yesterdays problems were nothing to do with Prestwick staffing !
The approach frequency failed.
Simple as that.
The first arrival changed to tower frequency when he realised all had gone quiet during his radar vectored ILS and completed a procedural approach from the PIK.
The 3 other arrivals (1 Ryanair and 2 PC12s),were routed (by us at ScACC) to Turnberry initially, the Ryanair had the least holding fuel, and was then routed to the PIK, half way there the frequency was restored and he was vectored for the ILS.
Operations then were restored to normal.
Those of you sitting on the ground were safest there until the approach radar controller had a frequency to use.
Obviously in a situation like this there can be a backlog, it was just unfortunate that Prestwick had 4 arrivals and 3 pending departures in a very short space of time.
Just one of those days when something relatively minor happened, and some people read more into it !
