Quite happy not to do that gentlemen although the comment was slightly
tongue-in-cheek.
Thinking about it a little more, then, the relevant aerodynamic variables with respect to a barrel-roll shouldn't come anywhere near the edges of the envelope during this manoeuvre though, should they?
And even if
we aren't, the aerodynamics isn't sensitive to \phi!
A dangerous assumption, perhaps, but if a 707 can do it, a 737 probably can. The aerodynamics isn't going to be fundamentally different:
