I agree its fake. The second crane doesn't look like it was pulling at that much of an angle to pull itself off the jetty(stabilizer sliding that far to go over the edge). It appears that the first truck fell right back in the identical place it first was (what are the odds of that?)
What kind of guy lets all those people stand near it while lifting something?
Funny thing is carne one went over and they all got right back around crane two.
