The AOPA will tell you the airport watch program is the solution, even though it
keeps happening.

No way to tell how many aircraft thefts have been averted because of
the airport watch program. They probably go unreported. Naturally when
a plane is stolen the media jumps all over it.

There are definite problems, thats for sure, which the AOPA constantly tries to dismiss, rather than address. That is because addressing them would cost money,
and pilots are so used to flying in large part on the taxpayers'
dime.

If securing an airplane means buying a $50 prop lock I doubt many
owners would object. Aviation has never been a cheap hobby. As far as
your comment about pilots flying on the taxpayer's dime, remember
pilots ARE taxpayers. And they're using a system (sometimes) that was
designed for airlines. If GA went away the cost would be the same, so I
don't see your point having any merit.
