When eight-year-old Aaliyah Purdy flew by herself from Newark, New Jersey to Charlotte in North Carolina her parents allowed Inside Edition to attach a hidden camera to her.
Aaliyah was seated in the back row of the plane, to make it easier for flight attendants to keep an eye on her.
But when the plane starts to get busy and it's time to hand out food and drink, it seems Aaliyah is quickly forgotten.
An Inside Edition producer left his assigned seat and moved towards the back of the plane to sit alongside the little girl without anyone so much as batting an eyelid.
The man was even able to give Aaliyah a chocolate bar without anyone noticing, or stepping in.

Mackenzie's mother, Rachel Miller, said: "He was able to touch her, he was able to do basically whatever he wanted."
