Dude, 70x5 can put a viewer very close to the action from 4 miles.

This is view from 86th floor of Empire State Building of the old WTC towers. Trump's view would be about 25 blocks further uptown and about the same level (68th floor).

With a telescope or decent binoculars, it's quite obvious you would be able to see bodies falling from those buildings.
