Can someone help me figure this out? From what I have found this 2007 Hawker has been registered twice, ELICE (5th one down on the left), and N521xp. My findings have shown that it was initially registered as N521xp and then re-registered as ELICE. Currently it can be tracked using N521xp which was the 1st registration according to my research. There may be a simple answer, but it is bugging the crap out of me.
