You may not have seen the picture from the Kershner book when you
wrote this, but write back when you have seen the barrel roll as
described by someone who is considered an authority in the field.

I've been shown two different ways to do a barrel roll.

The first was to pick a reference off one wingtip. Start pulling and
rolling toward the reference point. Once inverted you would be 90
degrees off original heading (pointed at the ref point). You continue
to roll and pull returning to the original heading.

The second way was to pick a reference point over the nose. Put the
nose slightly to one side of that point then roll and pull keeping the
nose the same distance from the reference point.

The first is the big loopy typy barrel roll - and a lot of fun to do.

The second is a much tighter roll without any loop.
