The Tedescos, twin brothers, each spent about three decades in the private sector working in electrical engineering and instrumentation design before they decided to kit out an old RV with an array of homemade signals collection equipment. Their aim was to create a mobile field lab for investigating UFO hot spots. Intrigued by their efforts, members of Harvard’s alien-hunting Galileo Project began talking with the Tedescos in 2021 and asked them to join as research affiliates. MARCO GIANNAVOLAChris Grooms, an Iraq and Afghanistan war veteran who was a deputy sheriff in Nebraska during an earlier multistate wave of mystery drone sightings from December 2019 to January 2020, gushed when I asked him about the Tedescos: “I don’t know how much you’ve talked to those guys. They’re freaking awesome.”Grooms joined the Tedescos last January, when the brothers publicly shared some of their findings from training the Nightcrawler’s sensors on a few of these unidentified drones.
