The aeronautics company founded by Microsoft co-founder Paul Allen provided the first look at the world's largest airplane based on wingspan. The airplane from Stratolaunch weighs 500,000 pounds, and rested on all 28 wheels for the first time, the company said in a statement. ?"This was an important step in preparing the aircraft for ground testing, engine runs, taxi tests, and finally the first flight," said Jean Floyd, CEO of Stratolaunch, in a statement.
The plane is the largest in the world based on wingspan, measuring 385 feet, which is longer than a football field. The Stratolaunch aircraft features two cockpits and six Boeing 747 engines. It's capable of carrying the weight up to 550,000 pounds.
Allen founded the company in 2011 as part of a plan to make travel to low Earth orbit more accessible. ?"Opening up access to low Earth orbit will deliver many benefits," Allen wrote on LinkedIn last year. "For example, we could use more satellites that would enable better understanding of why our weather patterns are changing and help increase agricultural productivity. And, we could study atmospheric chemistry more closely to better study and reduce the climate change."
Floyd says the aircraft will start testing at the Mojave Air and Space Port over the coming months, with plans for a launch demonstration in 2019. "This is a first-of-its-kind aircraft, so we’re going to be careful throughout testing and continue to make our pilots, crew and staff safe at the first place," said Floyd. Allen is among several tech companies with an eye toward space. Tesla CEO Elon Muskand, Amazon CEO Jeff Bezos both run their own aerospace companies — Space X and Blue Origin respectively.

難句解析
wingspan/?w??sp?n/n.翼展，翼幅
例句:Inflatable wings on other normal airplanes would also allow engineers to double the craft's wingspan in flight.一般飛機(jī)安裝了充氣式機(jī)翼后聚假，可讓工程師將飛行時(shí)的翼展增加到兩倍块蚌。
cockpit /?k?kp?t /n.駕駛員座艙; 斗雞場(chǎng); 屢經(jīng)戰(zhàn)爭(zhēng)的戰(zhàn)場(chǎng); 操舵處
例句：The window in the cockpit had blown in and the pressure dropped dramatically.駕駛艙的窗戶突然向內(nèi)破裂，氣壓急劇降低膘格。
The plane is the largest in the world based on wingspan, measuring 385 feet, which is longer than a football field.
從飛機(jī)翼展來看峭范，這個(gè)飛機(jī)是世界上最大的，達(dá)到385英尺闯袒，要比足球場(chǎng)還要長(zhǎng)虎敦。該句中的measuring是動(dòng)詞的-ing形式作伴隨狀語；which引導(dǎo)非限制性定語從句政敢。
