AMG65 and AMF
You have to chill mate.
No overheat here. And I do not mean anything personal.
But AMF's description should be supported by references to theoretical or experimental studies or even personal experience (if any). Otherwise, it looks like fiction.
See, for example, Tim Vasquez's analysis: no updraft higher than 40kt (about 4000 ft/mn), not "18000 ft/min, even higher" as mentioned, and no heat sink signature observed.
Of course, I don't intend to suggest that the pilots were not faced with a very severe situation flying in (or close to) bad weather without reliable airspeed indication.
