the Pelican is a free addition everyone gets (listed in the google text i linked), i doubt you actually have any aircraft your not supposed to have, its more likely a 3rd party addon caused you to think you did but … hey if they gave you the thing, fly it lol
its not like you went and pirated it, if They (ms/Asobo) added it too your account
i fear this will come back to haunt you later but cheers mate
