The concept of using children's voices for safety briefings is rumoured to have been the brain child of Sergei Chaliapin, Director of Aeroflot, and Director General in Russian State Information Technologies. He's held the post since about 2007/8 and is a devoted family man of great probity. He was asked to design a concept which would help distinguish paedophiles from passengers in the run up to the games at Sochi and for the benefit of Russian society as a whole. His solution was to incorporate a series of sensor in the arm rests of the seats on Aeroflot aircraft and then, by routing children's voices through the aircraft PA system, to be able to measure the electronic tinglings of delight of each passenger as he or she became aware of the childlike voices. These readings could, as in a lie detector, be fed to a central computer within the aircraft system which would enable the seat number of anyone who registered a suspicious reaction to be reconciled with their name on the load sheet. Thus the purported paedophile could be a marked man or woman at destination and dealt with accordingly.
Unfortunately perhaps, the technology for the broadcasts themselves has been used by other airlines. But in the absence of the original screening equipment, the likes of Air New Zealand do not possess the sophistication to put the announcements to the use for which they were originally intended. There was a suggestion a couple of years ago that the New Zealand government had approached the Russians with a view to recording some trial announcements in a baa like reproductive tone.
