zero-gravity flight

TNA 001, revised flight level three three zero.

复兴洞洞么, 修正飞航空层三三洞.

In a research paper published while at Nasa, he explained: "A zero emission, highly efficient, highly reliable, ultra-low noise VTOL capability would be a game changer compared with existing close proximity flight capabilities, for both unmanned and manned applications."

在一篇他任职NASA期间发表的论文中，他解释说：“与现有的短距离飞行能力（无论是无人还是载人飞行器）相比，零排放、高效率、高可靠性、极低噪声的垂直起降能力将成为游戏规则的颠覆者。”

Is JAL Flight Four Zero two leaving on schedule?

日本航空公司的四零二航班准时起飞吗？

Built by Mitsubishi, which manufactured the "Zero" fighter during the second world war, the flight highlights the growing capability of a Japanese aerospace industry that for decades has relied on the US.

这架飞机由二战时制造零式战斗机（Zero）的三菱（Mitsubishi）建造，凸显了日本航空工业能力的不断提高。几十年来，日本航空工业都依赖于美国。

In most flight conditions it is desired to maintain the sideslip angle equal to zero.

大多数飞行状态都要求保持侧滑角等于零.
