Would this plane have flown?

You would also want to contact your insurance company because most aircraft
insurance policies are restricted to "when a valid standard
airworthiness certificate" is on the airplane.

The insurance co's attitude was "spend what you have to, do what ever
you have to" to get the plane out of Mexico. If a pilot leaves a plane
in Mexico it can take months to get it back. The Mexican gov't has a
real hard time with pilots exiting that are not the pilot who flew the
plane in. Also, they know there is money in fixing airplanes and they
want to make real sure they get a piece of that. Everything in Mexico
requires lots of paperwork and every paper needs lots and lots of
stamps
