I have never seen a discussion of this (but of course neither the original
papers from the mid-80s). It has become common to presuppose their
conclusions, methinks, e. g. in the recent Naturwissenschaften paper by
Chatterjee & Templin which praises phugoid gliding.

What does phugoid gliding actually mean? Dropping oneself from a height to
gain speed before spreading the patagia?
