I’ve seen the original, longer video of this situation and declined to share it due to the fact that the child’s face is clearly seen. However, this version redacts his face.
In the longer video, the child runs down the airplane aisles and when compelled to stop, these screams issue forth. He cannot sit still in a seat and the longer video shows him standing on and crawling over seats until…once again, he is being asked to stop and the screaming starts. The video game cannot be started and he screams. He appears to be about 4 years old, maybe 5.
I think in this situation it would be justified for the airline staff to remove the family from the flight citing that the child is obviously not in an emotional condition to fly across the Atlantic Ocean for 8 hours. And I do think it is poor parenting to raise children who scream like they are being killed with a 14-inch Klingon danger to the guts when the issue prompting the screaming is really one of entitlement.
