Woman injured after football-sized mass of frozen human waste falls from plane

In what's described as the first incident of its kind in India, a woman has been injured after a football-sized mass of human waste fell out of the sky and crashed onto her.

Rajrani Gaud, from the village of Aamkhoh in India's Sagar district, was going about her usual chores when a "monster" chunk of ice smashed through her roof, reported the Times of India. She sustained shoulder injuries. 

Aviation experts believe the giant ice block was a ball of frozen poo and urine that fell from the toilet of a passing commercial plane.

Witnesses from the woman's village told reporters she narrowly escaped death.

"I was only 25 feet away from the spot where the monster came crashing down. Children and villagers witnessed the fall and then heard screams. We ran towards Rajrani's house and referred her to hospital," said a schoolteacher to the Times of India.

"The ice ball hit the roof first. Otherwise, it would have smashed her skull," he said.

According to an aviation expert, waste that leaks out of an aircraft toilet escapes in a liquid state, but will freeze upon contact of outside air. However, the chances of such a chunk of ice, known as "blue ice", reaching the ground unmelted is extremely rare.

If investigations confirm the substance to be blue ice, the incident will be logged as an aircraft accident and the victim will be entitled to compensation, reports the Times of India.
