I was a 111 Sqn Liney on Phantooms in the mid-eighties and when on Q the Ground Power was always plugged in & on to keep the INAS running. Sometimes a "leaky" jet was also hooked up to a set of nitrogen bottles too!
It was "sporty" enough just like that, but if you had a GTS wet start/fire you just KNEW it wasn't your day having to pat the smouldering noddy caps out.
Crazy days indeed!!
Best wishes for 2012
