Concorde grounded

All Concorde flights were suspended this week after Britain’s Civil Aviation
Authority withdrew the plane’s airworthiness certificate. British Airways had
continued flying Concordes after last month’s crash in Paris, which killed 113
people. Last week, French accident investigators said that a piece of metal on
the runway had caused a burst tyre, scattering fragments weighing up to 4
kilograms. The next stage in the chain of events had “yet to be determined”,
said the investigators.
