| 0:00.0 | In the year 2006, the United States Army deployed what's called a wide area motion imagery system, |
| 0:21.8 | sometimes called a whammy, on some of its manned reconnaissance aircraft flying in Iraq and Afghanistan. |
| 0:29.5 | This whammy called Constant Hawk allowed the army to test the more fundamental concept out, |
| 0:35.9 | to see if it would help them detect enemy ambushes and improvised |
| 0:40.0 | explosive devices, to things that were causing the army a great deal of trouble at the time, |
| 0:46.2 | increasing the duration of what was supposed to be a relatively short conflict. |
| 0:51.3 | To achieve this goal, the constant hawk leveraged a 96 megapixel camera alongside a supplementary |
| 0:57.8 | sensor suite that refined the images captured with that camera, making them clearer. It also |
| 1:04.5 | contained software that detected changes in patterns within the collected imagery. Specifically, |
| 1:11.9 | it allowed the camera to capture snapshots of part of a city or region over time to assess the normal order of things, |
| 1:18.6 | and then to note when something seemed to disrupt that order. |
| 1:22.6 | This information was flagged, with photos showing the seemingly out-of-place object or pattern disruptor, |
| 1:29.6 | sent to intelligence officers who would then determine if the weirdness was indicative of some |
| 1:34.8 | kind of explosive, of a base of enemy combatants, or something else, maybe even just a glitch, |
| 1:42.3 | or something the software would have no reason to know |
| 1:45.5 | is normal, like a civilian taking a different route to work because of a road closure. |
| 1:52.3 | Constant Hawk was successful enough that it eventually, after a few years in the field, |
| 1:57.3 | evolved into another project called Kestrel. Made by the same company as the previous |
| 2:02.8 | iteration, Logos Technologies, Kestrel was an upgrade to the constant hawk, replacing the single |
| 2:09.0 | 96 megapixel camera with six cameras tucked inside a gimbal, a container that allows the cameras |
| 2:15.9 | to rotate around an axis, which allowed the device, |
| 2:19.2 | if perched suitably high up, like on a plane or drone, to map out an entire city-sized |
