Okay, so this needs a little set up because this video starts rolling after the original incident occurred. But stick with it because that's not the story here.
So, apparently the women in tears was recently struck in the face by her stroller as a male flight attendant who you'll meet near the end of the video here ripped it out of her hands a little too violently. The flying stroller supposedly nearly missed hitting the baby in the head as well. So when tough guy flight attendant storms back onto the plane, an innocent bystander stands up for the women before flight attendant guy attempts to pick a fight with him.
Seriously, check this crap out I gotta believe this dude is getting fired.
