As most of you may already know, NC7861 is in an expired format, it should be N7861.
The search program changes old registration like NC, NX, etc to its N equivelant automatically, so you are actually searching N7861. However in aircraft registry database, the aircraft is registered as NC7861, so you won't get any result.
I'd like to hear your opinion on how to fix this, either change aircraft NC7861 to N7861, or change search program, get rid of the auto-converting.
