Well, in some respects, it helps your survival prospects if you are a child. This may be because children are more flexible, their bones less brittle. A smaller body mass may also mean that it is possible for a tree, or indeed a mound of seaweed, to break their fall. Also, they tend to be cocooned within their seat – a solid, rigid environment – and are therefore less likely to receive injuries than adults who have their heads and legs exposed. In 2007, for instance, three-year-old Kate Williams survived a Cessna crash in British Columbia because she was strapped into a child's car seat.

In 2006 a Slovak aircraft with 43 people on board crashed

Martin Farka˘s was found barely injured in the aircraft's lavatory

He had been saved by the call of nature.
