It is of course, not the biggest aircraft in aviation history — that honour belongs to the two Hindenburg-class airships, LZ 129 Hindenburg and LZ 130 Graf Zeppelin.
It's also shorter than the SpaceX Starship + Super Heavy combo is tall, (356 vs 397 ft), so it wouldn't even be the largest current aircraft. (Arguably a rocket isn't an aircraft, but Starship has large flaps, and Super Heavy has grid fins, so I think they count.)
