I was unable to get any registration numbers on this FA-18, but I thought I put the missing info in the correct format; the FAQ says:
"For military aircraft, list the serial in the registration field and the additional code if any in the code field. USAF and USArmy aircraft are listed with the full serial including the fiscal year, e.g. 43-12453 or 85-0035, for the US Navy use the full six-digit BuAer number, e.g. 160457."
I wasnt able to get the serial number either, so is this just a write-off?
