With your article on building the Airbus A380 you show a graph comparing other Airbus planes and the Boeing 747 with the new A380 (11 June, p 34). Features such as maximum speed and number of passengers are mentioned, but surely this graph should have two extra columns.
These would show average fuel consumption and carbon dioxide emissions per 1000 kilometres. Perhaps even better would be an approximation of the number of trees that would need to be planted to counteract the carbon dioxide emissions.
In this time of rising awareness of global warming and resource depletion, the costs of these “advances” in transportation should be clearly indicated and the need for them questioned.

Ben Bowie reports that Airbus can change the flight control software remotely. What an opportunity for hackers and terrorists!
