Help me trace a flight please.

I am looking to trace my first flight to the US.
The departure was from LGW on August 21st 1998 with a 'hotch potch' of an airline. I'll explain that.
A wee while ago there was a scottish airline named British Caledonian Airways (I know you know this already:D) which was purchased by British Airways and for a short while operated as Caledonian Airways.
The flight had a final destination of somewhere in Florida (can't remember where exactly), most probably MCO or SFB although it could have been any other, but the flight had a scheduled stop at Bangor Airforce Base in Maine to clear customs and immigration.
I believe the aircraft was a DC-10, but when I started to look into it I understand that Caledonian operated a number of Tristars also. It definately had a tail mounted engine.
So as to my question, I would like to trace this flight. http://www.lhr-lgw.co.uk only goes back to 1990 so cannot get anymore history here.
I also know that the return flight was two weeks later and again I believe this stopped at Bangor (although I cannot remember this so vividly).
So can anyone help me with this, this is one of the final pieces of my US history.
