My curiosity was aroused by your comments re "sandbox" ops and "hanging" at 1000ft.
Do you recall what the met and loading conditions were.
I am a bit interested in the mechnism of the "inversion" to which you referred??
We get similar temps in outback Oz often outside the "chart" limits accompanied by what we call "willy willies" (localised heating mini tornado) which provide some interesting flying.
