re Re: 87 4000Q vs 88 80Q

["Smith, Kirby A" <kirby.a.smith@lmco.com>]

"Dan Sinclair" <sinclair@prospro.com> listed some differences between the 80
and 90

<differences snipped>

another difference, in the quattros, is that the rear spoilers are
different.  The 90q has an inverted wing, while (whilst) the 80q has a
Kamm-effect  flush spoiler.
