BHOPAL: Almost ten months after an elderly tribal woman suffered a shoulder injury with a football-sized iced sewerage material that fell on her from the sky in Sagar district of Madhya Pradesh, a Delhi based aviation investigator B K Srivastava claims to have identified the commercial plane which ‘leaked’ it. Besides Sagar, Srivastava has also zeroed in on two other commercial planes that apparently which dropped huge ice chunks while flying over state’s Harda district on April 5 and in West Bengal on October 13 this year where villagers took ‘selfies’ with it.
He has pled director general of civil aviation (DGCA) to either investigate these mid-air drops or share radar images with him to corroborate his own findings. Srivastava has sent a letter to the DGCA referring incidents reported from Madhya Pradesh and West Bengal asking them to get it investigated by air safety office. DGCA’s air safety headquarters is located in Kolkata.
Initially, he had a doubt that these ice chunks could be a ‘megacryometeor’ – extremely large atmospheric ice conglomerations that fall under blue-sky atmospheric conditions but he is sure that they were ‘blue Ice’ – a term used in aviation context for frozen sewage material leaked mid-flight from toilets of aircraft’s on the flight route.
“I am confident about my findings, but this has to be ascertained by the regulatory body. By going through geographical coordinates and radar images we can pin point the commercial air craft which dropped the ice-chunks lavatory materials while flying overhead,” claims Srivastava who has done extensive research on mysterious ice ball dropping from sky. Experts say waste leaking out of a lavatory is in a liquid form, but gets frozen because of low temperatures at height at which airplanes fly. There is a fall of roughly 2 degrees for every 1,000-foot elevation. However, chances of such a chunk of ice reaching the ground is remote although not unheard of.
Once DGCA detects the plane, the woman who got injured in Sagar is liable for receiving a huge compensation as the incident falls under the category of ‘aircraft accident’ which mandates compensation to a victim under Aircraft (Investigation of Accidents and Incidents) Rules, 2012, said Srivastava. He has more than 45 years of aviation experience in field of air traffic control, aircraft accident investigation, airport planning, airport management and airport obstacle survey.
December 17: When blue ice injured a woman in Sagar
It was touted as a rare, celestial occurrence in Sagar district’s Aamkhoh village on December 17, till aviation scientists claimed culprit was a commercial plane which dropped a ball of frozen poo and urine from its toilet. Perhaps it was the first incident in India, where a person suffered injuries due to fall of ice from a passing plane. Victim, Rajrani Gaud, is alive only because the 50 kg ice chunk crashed into the terrace edge of her house before hitting her. Sagar incident was located at geographical coordinates 23°14’03.39″N, 78°53’06.08″E, which lies just below air traffic services route (ATS) of A-791 (Karachi-Kolkata-Bangkok), where the aircraft at height could be seen flying regularly from East to West or West to East when the sky was clear.
April 5: People in Harda believed it was the wrath of god
Two huge ice chunks dropped at Nausar village in state’s Harda district. Though nobody was injured, there was panic among villagers, who believed it was their deity’s wrath for breaking an age old tradition. Parmanand Khodre was working at his farm when the ice ball, weighing 100 kg crashed at a neighbouring field around 11.45 pm with a thud. When another crashed after two minutes, he was drawn to the spot by anxiety. Many villagers who gathered at the spot felt the same. Some even took broken pieces home. This incident was located at geographical coordinates 22°28’24″N and 77°12’29″E.
October 13: Villagers in West Bengal took ‘selfies’ with the blue ice
A big blue coloured ice block weighing about 8 to 10 Kg fell in a house in ‘Pakdaha’ under Sashan police station in 24 Pargana district (WB) at around 7.30 am. The ice piece broke into pieces and started melting. A big crowd gathered to watch the incident and many people took selfies and photographs in their mobiles. The ice block liquefied after some time. Many people collected ice & liquid samples unaware of the fact that it could be a frozen human waste leak from passing plane. Officials from Geological Survey of India, collected the ice/ liquid samples for the purpose of getting them tested.
Geographical Coordinates of the incident site (Pakdaha) are found as 22°40’55″N, 088°34’12″E. This place is located to the East of Netaji Subhash Chandra Bose International Airport Kolkata at a distance of about 10 Kms. Location of the site corresponds to the area where aircraft coming to land at Kolkata Airport from South (Hyderabad, Bengaluru, Chennai etc.) are flying almost parallel to Runway 01R/19L before turning left for carrying out an ILS approach on Runway 19L.
