A friendly supermutant named Erickson lives in the fuselage of this wrecked airliner. He can barter with you and also trains guard dogs. You can buy the guard dog of your choice or all of them. (Mutant hound, wolf, dog) These guard dogs can be sent to any of your settlements to boost defense and help against the attacks. Once you've purchased all his dogs, it will take time before he can train a new one.
There's also an advanced terminal leading to the cockpit. There’s a red industrial chest inside the cockpit but the its contents and the items in the cockpit are owned by Erickson. Take note that taking anything from it may turn Erickson and his dogs hostile towards you.
