Elon Musk secretly ordered SpaceX engineers to switch off the Starlink satellite communications network near the coast of occupied Crimea in order to thwart a Ukrainian surprise attack on Russia’s naval fleet, according to a report. The incident last year is reported in Walter Isaacson’s upcoming biography of the billionaire titled Elon Musk. With the comms down, the Ukrainian submarine drones packed with explosives “lost connectivity and washed ashore harmlessly,” Isaacson writes, according to CNN. Musk was reportedly motivated to foil the attack out of concern that a strike on Crimea would constitute a “mini-Pearl Harbor” and lead to Russia retaliating with nuclear weapons. The SpaceX boss apparently began to question his decision to support Starlink being used for Kyiv’s military communications when Ukraine started to use the tech in offensive operations against Russia. “How am I in this war?” Musk asked Isaacson. “Starlink was not meant to be involved in wars. It was so people can watch Netflix and chill and get online for school and do good peaceful things, not drone strikes.”
