iframe with instructables.com source

I'm trying to add a swf file in a step-by-step that was uploaded to instructables.com (https://www.instructables.com/id/Free-professional-wind-turbine-blade/step7/Spinning):
<iframe name="swf"
src="https://www.instructables.com/files/orig/FGQ/1M2V/HH11S2TK/FGQ1M2VHH11S2TK.swf" scrolling="no" frameborder="no" height="637" width="529"></iframe>

It's visible in preview but removed when saved.
I understand for external domains but for the same domain?

Is it a bug?
Thanks

The editor (and iframe code) might not accept .swf file without it being hosted first in a native window on another platform. An example of this is a YouTube video, which is a flash file hosted by YouTube which is externally linked to Instructables.

Can you try hosting the .swf in a player somewhere and copy the embed code over?

Hello Mike,
The swf includes the player and the video (camstudio screencast), see it at:

Forget the iframe, I got it to work using OBJECT tag in bold text here

I think I'bles does limit some of the HTML constructions you can use. Since they don't control the content of uploaded images, technically it's not from "the same domain," as you could incorporate any undesirable content without I'ble's control or consent.

Having said that, you could try just removing the method and host from the URL, and specify a relative URL instead ("/files/orig/.....").
