back in the late 1990s we were building a not so-secret new technology item for the Navy.
The item happened to be included as a itty bitty, completely indecipherable, blue bit, in the far far background of a photograph of our shop floor in our monthly employee newsletter ( at that time emailed )
within 1 hour of publication ; I received a ‘friendly’ telephone call from my counterpart in the Navy regarding said photograph.
Once informed our staff we wanted an Ordnance Alteration for deployment. Name was unclassified. Phones started ringing quite quickly then too.
