It is often said – usually to people like me who are terrified of flying – that the reason we hear about plane crashes in the news is because they so rarely happen. And yet, in less than a month, there have been four incidents involving aircraft.
First, a military helicopter collided with an American Airlines passenger plane in Washington DC on 29 January, killing 67 people. Three days later, a medical plane carrying a child patient and their guardian, as well as medical crew, crashed in Philadelphia, killing the five passengers and one person on the ground.
