The above says that the scenario that Bushman describes is the
same as Mr. Manic's, but it's not as simple as that. In Mr.
Manic's scenario, the magnet is dropped down a copper tube, and
a magnetic force opposing the motion comes with the current
induced in the copper tube. In Mr. Bushman's case, the magnets
are not dropped down a tube but appear to be dropped in air down
a stairwell or elevator shaft. There is a possibility that
current was induced in the metal of the building, and the field
resulting from that current might then have slowed the fall of
the magnets.

But also, the fields are different in the two cases. Mr. Manic
dropped a single magnet down a copper tube, while Bushman
dropped the more complex magnetic field of the two magnets bound
together down either the stairwell or elevator shaft. It is not
at all obvious that the two scenarios are equivalent. Certainly,
there is sufficient ambiguity that we cannot say for sure that
Lenz's Law can explain Bushman's claimed effect. Would the
induced field from the building infrastructure have been strong
enough to retard the velocity of the magnets?

The following quote was apparently invented to minimize
Bushman's claims since, as far as I can tell, he makes no such
statement in the video.

Bushman does say that he has signed statements from the nine
witnesses that the effect occurred as described. Of course,
according to scientific protocol, the statements and the document
describing the experiment are not evidence until they appear in
the public domain so that the experiment can be replicated.

But just the video description might prompt someone not bound by
secrecy agreements to try the experiment, especially considering
that Lenz's Law may not apply. It should be clear to anyone who
looks that gravity R&D has not been addressed publicly for a long
time now.
