这是飞机画出来的？

是飞机画出来的，但是用的是新方法？？
是一次成型的。不是原来飞机好像转来转去画的。

应当是按照喷烟圈的原理， 用每个字母的模子从机尾喷出来的。。。。。。对吗？

好像有点道理...我记得以前在中国的时候看国庆礼花，还能打出中文字来，估计难度比这高很多...

上面两位的高见-可能在多年后才会发生。
我们的想法可能会引导 skywriting 的革命。
以下是正在使用的方法：How High Do We Do Skywriting?
TRADITIONAL SKYWRITING - Accomplished by a single plane, maneuvering through the sky to form letters. The white smoke that remains like writing across the sky is composed of a special oil, which combines with the plane’s exhaust. The average message is up to six characters long.

DIGITAL SKYWRITING (SM) - Five to seven planes. They fly rigidly parallel and equidistant courses as nearly in perfect unison as possible. The message to be written is arranged on a master control panel, and as the planes fly abreast electronic signals cause the smoke-emission mechanism in each plane to release puffs of smoke accordingly. Digital Skywriting is carried out by a squadron of planes that are coordinated to print different segments of the message simultaneously. Every four seconds a new letter or logo is finished. The average message is up to twenty (20) characters and can stretch five to eight miles long.
