Yep!
Tried ...
--aircraft=CitationX --airport=CYOW --runway=25 --fg-scenery=
$HOME/Scenery-1.0.1
Take off, wheels up, and turn to 98, flying at about 2500, at about 260
IAS ... about 10 minutes or so and BANG!
As reported had hundreds of ...
CullVisitor::apply(Geode&) detected NaN,

For for the next run I added --log-level=debug

and got last output of ...

recompiled OSG, and added > templog2.txt 2>&1 to the command and
tried again... same POOF!!!
