RESIDENTS who live near Delhi Airport claim that human poo has been raining on them from planes flying overhead.

Last Friday, the country’s environmental court, the National Green Tribunal (NGT), asked a special committee to investigate the claims.

According to the India Times, the committee will be tasked with collecting samples and sending them for tests to find out whether it is human or bird poo.

The court has also asked for spot inspections of aircraft landing at the airport to ensure that their toilet tanks are not emptied while landing.

The investigation comes after multiple complaints from residents.

Last year, the same neighbourhood made several complaints about aircraft seeping sewage mid-air.

A tribunal ruled that “any aircraft, airlines and the handling services of registered aircraft” found dumping human waste in the air, or emptying toilet tanks before landing, would be fined Rs 50,000 (£579) each time.

Delhi isn’t the only airport to have these complaints.

Earlier this year, a woman who lives below the flight path of Salt Lake International Airport in Utah claimed her driveway has been the target of falling human faeces.

In 2014, a woman from Auckland, New Zealand, also claimed that her two-storey home and her silver car were covered in splotches of excrement dumped from a passing plane overnight.

But Patrick Smith, an airline pilot and the host of www.askthepilot.com, says that there is no way to intentionally drop poo from the toilet tanks of a plane mid-air.

The waste from aeroplane toilets is supposed to be stored in a tank in the bottom of the plane and a sanitation crew at the airport then empties the tank after arrival.

Patrick told Sun Online Travel: “There is no way to intentionally discharge the content of the toilets or waste tanks on any commercial aircraft.

“There are no such controls anywhere in the cockpit or cabin.

“The only way this could happen would be through some malfunction or perhaps an improperly secured waste access panel.

“Even with an open panel, though, the contents don’t simply pour out, so if waste actually is falling to the ground, something pretty unusual is going on.”

Planes use a closed waste system, which works like a normal toilet with waste flushing into a sewage tank, or a vacuum waste system that sucks the waste into the sewage tank.

Whichever system they use, the waste is emptied from the tank when the plane arrives at the airport.

Vacuum plane toilets were first invented in the 1970s by James Kemper, with the concept being introduced on Boeing planes in 1982.

Prior to this aeroplane loos used a blue liquid which pushed the waste into a storage tank, but this was problematic as it added weight to the plane and sometimes leaked in frozen blocks when flying over land and sea.

In fact, as recently as 2015, there were reports of frozen poo falling from the skies in the UK.

In October of that year, a lump of frozen poo fell 30,000ft from a plane and came crashing down into a retired couple’s house making a large hole in their roof.

Keith Mead, 70, and wife Ruth, 67, who were relaxing at their home in Wiltshire, rushed out when they heard a loud bang sound outside.

Initially, the couple thought there had been a car accident but were astonished when they saw the large frozen poo on their lawn.

The lump of frozen urine and faeces had allegedly fallen 30,000ft from a jet after a toilet on board had been flushed.
