I bet the pilot and weapon system operator are answering some tough questions about this incident.
A military fighter jet has dropped a replica bomb on to the roof of a working factory during a flight in Loiret (Centre-Val de Loire), injuring two people.
The Dassault Mirage 2000D jet [an example of which is shown below] had taken off from an airstrip in Nancy (Meurthe-et-Moselle), and was flying over a factory in Nogent-sur-Vernisson at around 15h20 on Tuesday April 10, when witnesses heard a loud bang.
It later emerged that a replica “bomb” had fallen off the plane and hit the Faurecia automobile parts factory, slightly injuring two victims who were working on the assembly line.
The bomb - used as a stand-in for the real thing in training exercises - was made of metal and plastic, and contained no explosives.
There's more at the link.
One can almost hear the other workers on the assembly line: "When we said 'Strike', this isn't what we meant! We're working as hard as we can! Stop bombing us already!"
