The “rubber box” or did Laura Keene indeed held Lincoln’s head?

The Ferguson route: I still think it is highly questionable whether Laura Keene would have been able to follow this route (in ca. 20 min), while there was complete pandemonium in the theatre.

   

The Gourlay route: I now think it is possible Laura Keene followed this route (if she was indeed in the State Box, which is IMO still questionable). She actually was not really in the 4 feet wide passage. If she was with her hooped skirt it seemed to me an extra difficulty (does someone know how wide her hoop was?). One point: was the outside stairway reachable as I’ve sketched? Or were there buildings preventing this?
