As you can see, the plane is not displayed in the browser, but perfectly visible, if we downloaded the flash drive to the computer.

What is the question exactly?
If it’s why is it not displayed once viewed from an html, make sure you have wmode=direct set into your swf embed.

A how to install this wmode = direct?

If you embed this code everything works fine in the html page,but how to make 3d content was visible in the browser for a direct link to the swf, for example on any forum?

<object data=“a1.swf” type=“application/x-shockwave-flash” width=“800” height=“600”>
<param name=“movie” value=“a1.swf”>
<param name=“quality” value=“high” >
<param name=“wmode” value=“direct”>
</object>

Unless the dev/webmaster behind the forum helps you or if there is some kind of upload widget with wmode option, you can’t.
