What is the minimum number of people required to manually pushback a 747? Similar to :
Is there a minimum number of people needed for an aircraft pushback?

After watching this video I wonder what would be the number of people required to manually push back a 747.


                
            

I know small aircraft is usually pushback by the pilot and if possible a wing walker. Large jet at large airport has a few people involved in the process. But manual pushback a large jet is a special event where you need lots of people. How many do you need?
The rope must be attached one end to the aircraft and another to some stationary point. Humans should push it onto the side from the middle point. This should amplify the force significantly, reducing the number of people required by at least the factor of ten or about, so I think somewhat all passengers could do, even if half of them is not fit (there are about 400 in three class layout and we need about 200 strong enough humans). Here is the description of the idea with all mathematics involved.
