I have a picture of a DL 738 in my web page but there is no visible N#. After a little bit of research on A.net I found out that the "nose" or fleet number that is on the tail and nose.. "3756" is actually registered as N3756. Even though the reg and fleet number is the same, my question is this.. It seems that the majority of the airlines use a 2,3, or 4 digit code to keep track of their aircraft without using actual N (or whatever country it is registered in) numbers and I would like to know if there is a web page or site that would list these numbers and their corresponding reg numbers? I already know all of NW's fleet numbers.
