Online retailer Amazon has released a video of drones which it hopes will soon be flying in home deliveries to customers.<br /><br />The company intends them to be ready for use in five years in the United States, although it still has to get approval from US aviation regulators.<br /><br />The drones, called Octocopters, would deliver packages weighing up to 2.3kg to customers who live up to 16 kilometres from the storage centres.<br /><br />Amazon is in need of a positive news story, especially in the UK.<br /><br />A recent undercover BBC investigation found workers were under “unbelievable” pressure which a leading stress expert said could cause “mental and physical illness.” <br /><br />Amazon says the safety of workers is its “number one priority”.<br /><br />The company has also come under fierce scrutiny for its tax position. Last year in the UK it paid £3.2m (3.8m Euros) in tax, despite its overall UK sales being £4.2bn (5m Euros.)<br /><br />In the summer, a petition of over 170,000 signatures was delivered to 10 Downing Street, the official residence of the British prime minister, demanding Amazon pay tax on UK sales.
