Neither you nor I (or anyone else for that matter), know exactly what degree of damage an aircraft would suffer if it were to fly through such a cloud.
To evaluate this all relevant factors would need to be known, vis: size and composition of dust particles, duration of flight through these particles, and effects of these particles on the aircraft and it's engines at a given speed and altitude/attitude.
Since these factors are not known (to anyone), common sense dictates that we should not put
any aircraft into such a situation.
Don't you agree?
