Claim: Real video of a Boeing 747 being launched from the top of a cargo plane.
Fact-check: Simulation video of 'Antonov An-225 carrying Boeing 747' shared as a real incident - FACTLY
Verdict: it is not a real incident. it is a simulation video posted by a youtube channel  with the title – 'world's biggest airplane antonov an 225 carry boeing 747  | x-plane 11'. both of them did not find a place in the last released 2020 list. hence the claim made in the post is misleading.
