Not really a daft comment as such, but I have my 5 year old daughter convinced that in order to get the aircraft to take off or land she has to press the up or down arrow (volume control) on the IFE handset. You should see her little finger jabbing away as we are racing down the runway .
Please don't - that sort of abuse tends to knacker the handset over time. It's a pain having to explain to the next passenger in that seat that they can't have any IFE for their flight as the handset's broken. Also, please can everyone return their handsets to the stowage when you're not using it, keeps them working a little bit longer........
