To Mr. Litton.
Lower windows 2' 8" from ground. Apertures 1′ 91⁄2" square.
Wide-enough for body of a medium sized person to be pushed through.

The initial velocity determines how far from a building 220' high a person lands. For 30' would be 8' per second.
Possible for someone to jump 8' in 1st sec. if normal person.
All that is required is to jump 8' in 1 second.
Same force required for throwing. I would have thought
probably 2 people.
I look at photo AF in Cl - lower down building
initial velocity required.

greater
Unlikely that person who fell over or was put over would
have sufficient initial velocity to land 30' out for building.
To Mr. Litton
Conclusion is baselon vårtical height of 220'. I speak of
initial velocity of 8' per second. Sidewind would not affect matter
too much. 8 per second is about 5 m.p.h. Wind can't be disregareded -
could push someone to one side or other of point of departure.
I look at photo R in Cl. Perched on railings, unlikely to be able to propek oneself 8' per second. Unless point of departure
near the shaft, more likely he was thrown than propelling self off.
To Court: In photo L then seems to be a ledge see also 2.

If one perches on railing very difficult to achieve 8' second. With another footing quite possible to achieve 8' per second.
