Coff,
STARTREK was a 70 Sqdn Callsign for a Scottac formation as I recall. GUINNESS would relate to 47SF I suspect, considering their usual "après luft" lubricant of choice (well, certainly a particular Scots Co). I can certainly confirm that I once did a trip in the Gulf with a 47SF crew who used the callsign ALBERT 01. Off for a few days tonight, but couldn't resis a quick response. Keep it going Truckies.
