I was intrigued that there is video from "a passenger's mobile phone"? As a member of the SLF community, I thought they should be switched off? Some passenger has survived explosive decompression but ignores the safety brief and decides to risk switching on their phone?! Or am I wrong about this, do Qantas have a "phones OK" policy?
Don't know about Qantas, but many phones have a "flight mode" where the radio is inactive but the camera and other applications can be safely used. Whether that is allowed also during start and landing seems to vary between airlines - some demand all electronic devices to be switched off in those flight phases.
