Thank you, Ugly
Whenever there is no "mayday" call, or any other call, it's CFIT or poor judgement when down low or incapaciation. And I have personally witnessed two gee-loc incidents in the early days of the Viper. Back seat for one and watched another in my flight for another.
I have to wait for the report like all of us, but I can't see some mechanical problem with the basic airframe or motor.
