The document discusses the safety of air travel by examining several plane incidents and accidents. It summarizes three incidents where planes vanished - Malaysia Airlines flight 370 in 2014, Air France flight 447 in 2009, and EgyptAir flight 990 in 1999. For the EgyptAir flight, the US investigation found the first officer deliberately crashed the plane, while Egypt's investigation blamed mechanical failure. The document also provides statistics showing that air travel is very safe, with a fatality rate of 0.003 per billion km travelled from 1995-2009, and only 1 fatality for every 287 million passengers on UK airlines, which is safer than the 1 in 19 million chance of getting hit by lightning. However, it questions whether flying is safe enough
