Well, by not flying any differently I mean it didn't shake or throw anything out of balance. On that same note, in the Mustang if you have a fouled plug you feel as if the motor is going to jump out of the mounts. I've seen a bird strike on a T-6 wing increase the stall speed to around 110mph, and another bird strike not affect it at all. In both cases there was enough damage to down the airplane several weeks for repairs.
