Fly Through Historic Ford’s Theatre

[AussieMick]

This has probably already been discussed ... but how long did it take from the President being shot to him being removed from the box ? (obviously theres going to be some approximation and differences of opinions ... but I think we can get a good estimate).
My question is due to me imagining how long it would take to get a window shutter (of the suitable size) pulled down and dragged to the box.
The other issue is ... I assume that window shutters were on many buildings in the area, and would the theatre have had shutters ... probably?

It could be that Lincoln was carried from the box by two or even four people (holding arms and legs) and laid on a shutter (or similar) outside the box. I'd be surprised if the box itself (cramped and with various furniture) and the door to the box allowed for much maneuvering.
