The plane is 107 feet from nose to tail-as big as a commercial jet seating 100 passengers, but with computers and instrument bays occupying most of the interior space and only a few Windows.

这架飞机从机头到机尾，全长107英尺，大小相当于一个可乘坐100名乘客的商业客机，但计算机和仪表舱占据了绝大部分内部空间，只有几个窗口。

Smoke and flames raced through the aircraft and, moments later, the plane nose-dived into the Everglades.
