BBC Today Programme: Bomb threats and airport security in Europe

The risk appetite for airlines is always going to be incredibly low. It is baked into their safety procedures and it's baked into their security procedures. So there isn't really all that much that individual airlines can do... It's worth highlighting that the airports that these planes have flown from all have the most advanced technological systems and highly trained operators working them. There are overlapping layers of security... So it really has never been harder to get a bomb onto a plane."
