There is additional trouble for embattled United Airlines as a man was stung by a scorpion on a recent flight from Houston, Texas, to Calgary, Canada. The passenger who was stung, Richard Bell was returning from vacation with his wife, Linda and were flying in business class. "Something fell on my head so I grabbed it," he told Inside Edition. "My neighbor said, 'That's a scorpion, they're dangerous.' So I dropped it on my tray, then I went to grab it again and that's when I got stung."
