Removing engines from a plane (Image for reference)

[Ryubunao1478]

So I watched a video made by JRSchipol titled "A Distant Echo" where it's a short cinematic film about plane crashes such as Air France Flight 4590 or Egyptair Flight 990. But one scene stand out the most for me. On the beginning part of the video, it shows an El Al Cargo B747-200F with no engines (Reference to El Al Flight 1862, a cargo plane that took off from Amsterdam that crashed to an apartment complex after engine 3 broke off and hitting engine 4, taking it aswell.) First I didn't mind it, but now I wonder, how did he removed the engines from the airplane? Does he use blender to modify the aircraft into having no engines and retexture the wings afterwards to make it look like it's torn off? Is it just removed while editing? Did he use a 747 model that already has no engine 3 and 4? I need some answers. Image below for reference.
