The danger from the phone falling on the plane

Passengers of QA380 flights of Qantas Airways, Australia are required not to find the dropped phone on the plane to avoid the risk of explosion.

According to the Register, the cause of the announcement was that the Qantas flight crew from Sydney, Australia to Dallas-Fort Worth, Texas, was alerted to "smoke in the cabin" in May.

The Australian Traffic Safety Agency (ATBS) investigated and found that the culprit was a phone stuck below, crushed by the business class seat when passengers moved their seats to search, causing a short circuit and make smoke smoke.

When the crew got it out, the phone was no longer smoking, but "the burning scent still remains in the cabin," the ATBS representative said August 25.

The phone burns due to a lithium-ion battery short-circuited when pressed. The flight crew had put it in a water bottle, inside a metal box. ATSB said that in this emergency situation, the crew had very good improvisation.

Qantas Airways is one of the 10 best airlines in the world in 2016, according to the evaluation of Skytrax - organizing the assessment and ranking of the world's largest airlines.

"We ask passengers to keep an eye on the phone in their seats, and if to fall into the slot, notify the crew, not to move the seat arbitrarily," Qantas said.

"We find this is a common problem on long flights, in the business class, when passengers often leave the phone next to them when relaxing and dropping the seat".

Earlier in September, a similar announcement was also issued by British Airways and Cathay Pacific on flights, according to the Telegraph.
