Surely it is safe to presume that while the process of assembly and tuning etc may take 10 days start to finish for each JetPack, as it is a production line several JetPacks will be being built at once. It is not a case of start one and build it then start another 10 days later.  From even a quick observation at the AGM it looked like the factory was set up to do at least 3-5 simultaneously.

So, once again, this is not a story. The sky is not likely to be falling.  There is neither a conspiracy nor gross incompetence at work.
