My point is carbon fiber isn't the same as the metals used in previous engines and airframes. If a RR turbine can explode in flight due to becoming unbalanced due to a bad bearing, what can a quad do to a CF fan and, more importantly, the CF wings and lifting devices installed on those wings? How much of an impact would it take to crack the surface and start a CF panel's delaminating? Once that starts, how long until the panel fails completely? I know aircraft structures are tested for flexing stress but I haven't seen anywhere where they are tested for impacts.
Granpooba, how fast was that engine running that you saw the frozen birds fired into? Ground idle, flight settings or full throttle? Engine speed can make a difference on the results. Think car hitting concrete barrier at 30mph and then at 100mph. Faster is going to give a totally different result than slower. Since the manufacturer doesn't normally give the testing parameters, we will probably never know
