I was given the choice of the Ultra or Excel. I took the Excel. I spoke to one other guy and he got the call on the same day and he got the Hawker, so I don't know what you will get. I think it just depends on their needs.
From what I was told by one of the people who schedule interviews and other related things is that when they interview you they put a particular aircraft on your resume. If it is only that one a/c, that is what you get. If it says "any" or has more than one choice, then you are offered what is needed at the time or whatever they wrote on your resume.
I know that alot of the guys/gals are being put in the ultra and excel lately, but you never really know.
