Rajrani Gaud, a 60-year-old woman in Sagar district of Madhya Pradesh, suffered a shoulder injury last month after a chunk of ice, which was almost the size of a football, fell on her from the sky.

According to a report in The Times of India, the incident which took place on December 17, has now caught the attention of aviation scientists who believe the ice could actually be frozen poop and urine which was unintentionally dropped from a commercial aircraft. Experts also said that this could be the first such incident in India where a person was injured from a falling ice from a plane.

Eyewitnesses told the TOI that Rajrani was alive only because the ice first hit the roof of a house before it struck her.

The TOI report further states, "It could have either been `Blue Ice' (a term used in aviation for frozen sew age leaked mid-flight from an aircraft's lavatory waste system) or a megacryometeor (an exremely large chunk of ice formed under unusual atmospheric conditions). An aviation expert said the waste leaking out of a lavatory is in a liquid state but gets frozen because of the low temperatures at the height at which airplanes fly-there is a fall of roughly 2 degrees for every 1,000 feet elevation. However, the chances of such a chunk of ice reaching the ground is remote although not unheard of."

The incident however was not officially recorded and no probe into it has been initiated.

An expert however said that if the ice was blue ice, the incident would be an aircraft incident and the victim would be entitled to compensation, adds the report.
