In the video, Hitler rants about the release of Microsoft's Flight Simulator X, citing issues within the game as well as the lack of certain features in the demo. Like most of the early Downfall parodies, it was taken down in 2009 by Constantin Film during the 2009-2010 DMCA crisis.
DReaperF4 commented on his channel that he will not be reuploading the original video, because he received a final warning from YouTube. Instead, he uploaded it on Megaupload, only to be later removed. However, another YouTube user, Twix101, manage to download it from Megaupload before it got removed and reuploaded it under the name of Hitler critica FSX. On April 2012, Twix101 closed his account and the video was no longer available on YouTube.
On 7 July 2012 MabusParodies reuploaded the video after he downloaded it from a link provided by DReaperF4 on his channel. Both parodies gather views slowly.
A mirror of the English-subbed version of Sim Heil was uploaded on June 2011 by the Russian Know Your Meme site. As of now the original author hasn't stated any plans on bringing the video back up.
- The scene used in Sim Heil starts at the moment when Traudl and Gerda enter the hallway. The future parodies no longer include this scene, instead they start when Krebs begins to speak.
- Despite being credited as the earliest known parody, a German-language parody entitled Mein Kampf um Mathilde was uploaded on 19 July 2006, roughly a month earlier. The latter video, however, was a humorous fan dub rather than a subtitle-based parody which would be a basis for future Downfall videos. It can also be noted that this was possibly the first to make use of scenes besides the Original Bunker Scene, such as the part when Hitler asks Gunsche for Fegelein.
- An even earlier parody entitled La Caida (La versión No Oficial), with Hitler complaining about his food bill, was uploaded on 3 February 2006. As of January 2013 the latter parody has garnered over 100,032 views.
