Do I need permission from an aircraft owner to publish pictures of
their airplane for profit? I want to take pictures of airplanes and
publish them commercially, on the web and in print.

Assume the following:
1) I am in authorized areas when I take the pictures.
2) I am not taking pictures of the owner or any people.
3) The photo does not contain any company logos or other copyrighted
images.
4) The N-number can be clearly seen.
5) The photo is of the outside of the airplane.
6) The aircraft will not be touched.
7) The aircraft is airborne, on a public-use airport, or on public
display.
8) The aircraft will be US-registered, in which the owner of the
aircraft can be found publicly in the FAA aircraft registered database.
9) I will be the photographer.

EG: Does Airliners.Net get permission from the aircraft owners to
publish their pictures. They have some very nice pictures that you can
buy.

Thank you in advance for your advice.
