Anyone who’s ever flown on holiday knows that there are a number of rules passengers must follow when flying.
Tray tables and seats must be upright on take off and landing to prevent holidaymakers being blocked from exiting their row during an emergency.
For a similar reason the windows must be up so that your eyes are adjusted to the light outside if you crash.

And, smoking, of course, is not permitted on the aircraft – as one man found out when his flight was delayed due to lighting up.
But, before the plane can soar into the sky you also have to put your mobile on aeroplane mode so no calls or messages can come through.
Lots of planes now offer Wi-Fi packages when in the air so why is it that your phone must be unreachable during take off?
Doug Drury, the Head of Aviation at CQUniversity Australia, explained in an interview with The Conversation.
He noted: "Personal electronic devices can emit a signal within the same frequency band as the aircraft’s communications and navigation systems, creating what is known as electromagnetic interference.
"But in 1992, the US Federal Aviation Authority and Boeing, in an independent study, found no issues with computers or other personal electronic devices during non-critical phases of flight.
"The US Federal Communications Commission also began to create reserved frequency bandwidths for mobile phones and aircraft navigation and communications – so they do not interfere with one another."
So, while this should mean we don’t need to go on aeroplane mode it’s still not the case – thanks to 5G.
Apparently the mobile phone usage of 5G bandwidths is much closer to that of airline systems.
Doug said: “The aviation industry points out that the 5G wireless network bandwidth spectrum is remarkably close to the reserved aviation bandwidth spectrum, which may cause interference with navigation systems near airports that assist with landing the aircraft.
"Airport operators in Australia and the US have voiced aviation safety concerns linked to 5G rollout, however it appears to have rolled out without such problems in the European Union.
"Either way, it is prudent to limit mobile phone use on planes while issues around 5G are sorted out."
