Entirely predictable, but ultimately someone is to blame for everything that goes wrong other than a Tsunami, and even then it's their own fault or the authorities for allow them to live near water!!
Bits fall off aircraft and CDG is amongst the worse in terms of ramp and taxiways for rubbish, i have seen dogs running around for 5 hours with no one doing anything about, i have very nearly taxied over suitcases shed from speeding baggage trucks, even if a whole flap section fell off an aircraft 50% of the pilots would be unaware because they use French & English in equal measure, so half the time you don't have a clue whats going on!!
Even if you report something the best you'll get is "I call you back"
