The FAA recently changed their rules relating to the approval of drones for flight testing in the US and now the Amazon Drones have been given approval for US flight testing.
Amazon recently received approval for their previous Amazon Drones after months of waiting, although this was not good to the company as they were now using a new drone which needed approval.
Luckily this time the Amazon Drone did not have to wait months to get approval by the FAA in the US, just a few weeks and the company now start testing their drones out in the US.
Amazon intend to use their drones to deliver parcels to customers, although it could be a few years yet before out parcel start being delivered by drones.
