The young Canadian girl who died on an Air Canada flight to London was on her way to Nigeria to celebrate Christmas. The 10-year-old, who has been identified only as Madra, suffered from sickle cell anemia, a rare blood disease which makes those who have it susceptible during air flight. In such instances, red blood cells change into a crescent shape that can disrupt blood flow, preventing oxygen from reaching nearby tissues. Authorities have not as yet however stated a cause of the little girl’s death. CBC
