Pedro Cruz didn't just live through the wreckage that Hurricane Maria left in its path in Puerto Rico back in 2017. He watched the commotion in his hometown of San Juan by flying his drone overhead. Maria made landfall on the southeast part of the island around 8 p.m., Cruz recalls in an interview with Popular Mechanics. Once the storm subsided about 20 hours later, he began his mission to find his grandmother. Since the infrastructure was completely decimated, he had no cell phone service to check in on her.
