Mystery Solved? Missile Launch Could Be a Jet Contrail
謎のミサイルと騒がれた事件は，ジェット航空機の飛行機雲に過ぎない？　FOXニュース

According to a post on ContrailScience.com, the visible exhaust from a jet engine, a trail of condensed water vapor
called a contrail, resembles a missile trail when seen from some angles.
The confusion between a missile launch and a jet plane launch is caused by several common misconceptions, the site
notes, explaining that the angle of launch, the direction of flight, and even the shape of the Earth can lead to the
illusion. And indeed, when you look at certain images of jet launches, they do look a fair bit like missiles.
ジェット機の上昇過程で出来る飛行機雲は，観測角度などの場合によってロケット発射のように見えることがあって
屡々ロケットの打ち上げと誤認されるが、

The site's author goes on to note other factors that could connect the unexplained launch to a jet engine. There's no
no bright rocket flare, just a few flashes of sunlight, and a sunlit trail. Plus the unexplained craft is incredibly slow, the
site notes, while rockets move incredibly fast.
Meteorologist Kevin Martin of the Southern California Weather Authority is a believer in the airplane theory, too.
ロケットの噴射口のフレアとか，上昇速度（ロケットは高速，ジェットは比較的低速で上昇）で見分けることが出来る。

"We see this often when the flights come at the right time, however, some people are just out to witness it at the right
time," Martin told Examiner.com in Los Angeles. "We had strong winds up there as well as really cold temperatures from
a passing storm system. This also had an area of upper level moisture ... where airliners fly."
「強い風と寒気の存在、上空の高い湿度などで、そういう風に見える飛行機雲が出来る場合がある」
