Mind you, if it was a type which was often aerotowed on a belly hook,
and if the pilot knew what s/he was in for, and had suitable
experience, then it wouldn't worry me greatly.

The same holds true for aerotowing an L-13 by the tail tie down.

I suppose it may be possible to install a tow release in the tail
or tie a towrope on the tail tie down, and then aerotow an L-13
tail first. If someone had tried this in a wind tunnel first,
and had lightning quick reflexes, and adjusted to a suitable
CG, perhaps he could reliably fly it on aerotow tail first, facing
rearward, and upon release, do a horizontal hammerhead type
manuever and then fly normally.

If you saw someone do this a dozen times, you might conclude
and if the pilot knew what s/he was in for, and had suitable
experience, then it wouldn't worry me greatly.

With the appropriate training, conditions, and experience,
one can fly an L-13 tail first, or fly the Wright flyer. This
is trivially true. Of more interest is the relative ease
of towing forward vs. rearward (front vs. CG hook) and the
associated things to be cautious about.

I'm waiting for someone to post that aerotowing with a CG hook is
easier and requires less training and experience than towing
with a nose hook. As yet I haven't seen this claim...

As usual, there have been several outstanding posts of firsthand
CG tow experiences, and I've been most appreciative for these...
