The emerging sub-genre of public service announcements about geological surveys—apparently offered not just due to FAA regulations, but to quell the growth of potential conspiracy theories—continues with this heads-up about a “low-flying airplane” over parts of Virginia and North Carolina.

Of course, beyond the idea of simply preempting the development of new conspiracy theories, the work being done by the project is fascinating in and of itself: “Instruments on the airplane will measure variations in the Earth’s magnetic field and natural low-level radiation created by different rock types near and up to several miles beneath the surface. This information will help researchers develop geologic maps of the area that will be used to better understand sand resources and underground faults in the region.”
While we’re on the topic of the Virginia/North Carolina border region, I’m reminded of why there’s a strange “notch” in the state line, a story “that mostly involves collecting taxes and avoiding swamps”: “The rough and rowdy inhabitants living close to the border told North Carolina tax collectors they lived in Virginia, [Gates County historian Linda Hofler] said. When the Virginia tax man came, they said North Carolina was their home.”
