The Amazon announced the testing of a new service delivery, providing distribution with small unmanned helicopter 30 minutes. These small tetraptera can carry weight packets up to 2,2 kilos and will fly within a range of 16 kilometers from the company's warehouses. The concept may have theoretically many problems, due to weather conditions, weight or cost for example, but the company promises that all of them will be solved once it becomes officially available to the public in coming years.
