Amazon.com Inc. on Sunday showed off a drone prototype for the company’s planned 30-minute unmanned delivery service. It is the first new prototype Amazon has shown publicly since it announced its drone plans two years ago, also on the day before Cyber Monday, one of the retailer’s biggest days for shopping. The new prototype combines elements of a helicopter and an airplane, including a rear-facing propeller. Amazon claims the aircraft can fly 15 miles and can reach an altitude of nearly 400 feet. In a promotional video posted on its website, Amazon showed the drone storing a package within the fuselage rather than extended below as in a previous design. Looks overbought. Suppose to see a correction with target price at $650 per share
