Upright trays follow up
A letter in response to the article in the Economist I mentioned a week back:
SIR – The bright-yellow lifejackets are not intended to act as flotation devices. They are there to make it easier for the recovery services to spot the bodies strewn across rough terrain. (I was once asked to put on a life-jacket over central Germany, some 300 miles from the sea.) And the advice to adopt a head-down fetal position in the event of a crash landing does nothing to preserve life, given that the stall speed of a modern airliner means it will connect with the ground at terminal velocity. However, the position does tend to preserve dental data, useful for identifying dilapidated corpses.
