Well, you see, the *real* reason for the SSN requirement is because the
FBO -- bless their heart -- wants to make sure you would be covered by
disability payments out of the U.S. Social Security system should you
get badly injured in an aviation accident, instead of their insurance
carrier footing the bill.

Beats me why they'd require the SSN, especially since it was never
intended to be a national identification number, and I don't think the
Social Security system is a particular concern of the FBO...
