????然而，航天業(yè)內幾乎沒有人相信聯邦航空管理局會在期限內放開限制。安全保障對監(jiān)管和技術領域都是一項挑戰(zhàn)，而聯邦航空管理局尚未提供關于商用無人機的許可、監(jiān)督、安全審查的指導方針，更不用說如何解決諸如可靠性和保險（到時會有很多很多的保險）等其他的責任問題。這讓觀望何種無人機能夠在領空飛行的研發(fā)者們處于很不利的位置。

????不過根據貝佐斯的說法，亞馬遜的研發(fā)團隊正在努力把年費79美元的會員的送貨時間縮減到半小時，至少在靠近物流中心的選定區(qū)域內實現這一點。貝佐斯在《60分鐘》節(jié)目中的訪談短片中顯示，包裹正在公司曲折的倉庫中前進——那是地圖上近100個亞馬遜倉庫中的一個，然后被放入特殊定制的黃色箱子內，通過傳送帶迅速來到等待著的亞馬遜八旋翼直升機下。直升機抓緊箱子，沖向天空，穿過田園鄉(xiāng)間，輕輕地將貨物放在收件人的房間外面。

????實際上，無人機作為商業(yè)工具的過渡時期也許并不會這么輕松順利，但是貝佐斯確信Amazon Prime Air這樣的服務是未來的趨勢。“它會派上用場的，它會成為現實的，而且會非常有意思?！保ㄘ敻恢形木W）

????However, few within the aerospace community are confident that the FAA will meet that deadline. Ensuring safety is both a regulatory and technical challenge, and FAA authorities have yet to provide guidelines on how commercial drone operators will be certified, policed, and audited for safety, not to mention how other issues of responsibility like liability and insurance (there will be lots and lots of insurance) will be resolved. That puts UAS developers at a disadvantage as they wait to see what kinds of drones will be allowed to fly in this new drone-enabled airspace.

????But according to Bezos, Amazon's R&D team is pressing ahead with plans to reduce delivery times for members of its $79-per-year program to just half an hour, at least in selected areas that are near enough a fulfillment center to allow for it. A short video screened by Bezos during the 60 Minutes segment shows packages snaking their way through one of the company's labyrinthine warehouses -- one of the nearly 100 that Amazon has scattered across the map -- before being deposited in special standardized yellow containers and sped along a conveyor belt until one comes to rest underneath the belly of a waiting Amazon octocopter. The drone latches onto the container and whisks it skyward, traversing an idyllic countryside before depositing it gently outside the recipient's house.

????In reality the transition to drones as commercial tools might not be quite so seamless and easy, but Bezos is convinced that services like Amazon Prime Air are the future. "It will work, and it will happen, and it's going to be a lot of fun."????????????????
