Answer:
Yes, because the trainer took reasonable care in training his pigeons.
Step-by-step explanation:
The granted verdict claims the innocence of the person being accused, in this specific case it has to be granted since the trainer as it says took reasonable care in training his pigeons, which means that he never had any intention of affecting others with his actions, besides the unfortunate events were started for an unexpected action of a pigeon, but at the end, it was the truck the one that destroyed the plane.
