Obviously the stall is not intentional.
It is caused by loss of control.
Loss of control in that type aircraft is almost always caused by something totally beyond the control of the crew and the equipment.
Turbulence, equipment failure, etc.
A line of severe thunderstorms is not where you would look for that perfect world.
I agree. Thank you for your very informative posts....a pilots perspective is always different from a engineers/technicians. Some design and maintain them..... others actually have to fly them.
