A drone crashed into an apartment building in Richardson, Texas, in February, causing significant damage to the building. The incident was caught on camera by a bystander who witnessed it. Amazon issued an apology and is investigating the cause of the malfunction. The company has been working with other companies to pilot drone deliveries. This incident raises public safety concerns about flying heavy autonomous drones over homes, raising calls for stricter oversight and clearer operational safeguards. The Federal Aviation Administration has been increasing enforcement of drone safety rules following past incidents. The drones are designed to safely navigate densely populated, complex environments but are not fail-proof.
