Multiple congressional committees have obtained and are scrutinizing the 30-page report, produced by the Multi-Agency Collaboration Environment (MACE), a part of Sierra Nevada, a major Department of Defense contractor. The report claims to rely on social media postings, commercial satellite imagery, and cellphone location data to draw the conclusion that some sort of “hazardous event” occurred at the Wuhan virology lab in October 2019—an event that allowed COVID-19 to escape. It’s a theory that has gained currency on the political right and in the upper tiers of the Trump administration.

But the report’s claim centers around missing location data for up to seven phones — and in many cases, less than that. It’s too small a sample size to prove much of anything, especially when the same devices showed similar absences in the spring of 2019. The MACE document claims a November 2019 conference was canceled because of some calamity; in fact, there are selfies from the event.

What’s more, imagery collected by DigitalGlobe’s Maxar Technologies satellites and provided to The Daily Beast reveals a simpler, less exotic reason for why analysts believed “roadblocks” went into place around the lab after the supposed accident: road construction. The Maxar images also show typical workdays, with normal traffic patterns around the lab, after the supposedly cataclysmic event.
