Here is an interesting video clip from 1943 showing the take off of a B-35 during testing.
It shows much more ability to get airborne than the following B-36. When I watched that B-36 video clip in my other post 'Six turnin' and four burnin', it reminded me of the Spruce Goose film clip.
That wing area obviously gave a lot of lift.
