Buvenbee,
Nah, don't worry, you haven't upset anything. It's just EXC's demise has been mentioned quite alot and very recently in R&N.
"Company X" became an effectionate term for those of us that had lost our jobs - X company - eXcalibur - get it !!!!??
A fab company, a fantastic workforce, a quality product, great looking brand new A320's and a hell of alot of fun...
As Jet Dragon mentioned, most of the aircraft were then leased by Airtours when EXC collapsed..
