"The FBI called and asked whether a plane took off or landed that had 'N 90' as part of its number," said Jennifer Essary of Natchez-Adams County Airport operations. "We don't have anyone on the field with that number." Anyone know what the number was on the stolen cropduster? Of course, they could repaint a new number on it...but it would be handy info for the public to have, don't you think?
