One considers missiles as being very powerful, and they can do a great amount of damage. For example, the missile armed to Apache helicopters can do an incredible amount of damage to targets as powerful as tanks and enemy troops and weapons. One would consider that the transport of such weapons would be done with the greatest amount of care and without involving any danger. So how would you feel if you came to know that a live missile was sent over long distances by normal parcel post by mistake, and was only detected when the parcel was opened in Britain (link to article):
The 70 mm Flechette rocket travelled 3,500 miles from Afghanistan to a Royal Air Force base inside an ordinary package, triggering a full-scale alert, The Sun reported. The missile, used by Apache helicopter crews, is said to be one of the most powerful rockets in the world. When it was opened at Wattisham Airfield, in Suffolk , more than 70 defence workers had to evacuate as bomb disposal experts rushed to the scene.
Britain's ministry of defence documents show engineers servicing a gunship chopper at Camp Bastion declared its missile launcher broken. But they did not notice it had a missile in it.
