How long is that hallway?

They made it from the west doors to the library awfully fast. Did Frey run or walk?

It is not as far as it seems. You can do a time of it while watching Eric in Columbine as he does walk right that way. It takes him about 11 seconds to go from the doors to the library entrance.

He is by the doors at 50 seconds in. Then around a min (When at the locker) they are right outside the library

Yes, very short distance. 11 seconds does sound about right.

The school looks bigger in pictures. I didn't realize that Eric was anywhere near the library in that video, that makes it even more disturbing.
So is the library right over the cafeteria? If the propane bombs would've worked, would the library have collapsed like they planned?

Everyone talks about how large the school is but it isn't really all that large. My HS was a lot bigger. And yes the library was right over the cafe. Not anymore of course

People who know about bombs have stated that even if they worked they wouldn't have brought down the library to the commons.

If you look at the FBI Diagrams they include an approximate scale which measures about 25 feet from the outside west entrance doors to the inside west entrance doors and about 75 feet from the inside west entrance doors to the library entrance doors.

The North Hallway from the inside west entrance doors to the inside east entrance doors is about 360 feet.
