Read the Door

 

Lieutenant Brian Dalrymple from Richmond (VA) Fire Department sent in these photos that he uses for forcible entry training. Take a look at the door, determine how you'd force it...

Did you focus on the carriage bolts? Did you realize that it was an inward swinging door?
(Come on, at least one person must have fallen for it...)

In this setup, cutting the bolts will not accomplish much, it certainly won't open the door. The bolts are only there to hold the hasp for the padlocks. The presence of the padlocks eliminates being able to manipulate the drop bar from the outside (after making some sort of opening.)

To top it off the drop bars are even set into the walls a bit on either side.

It's another setup you don't find every day. A simple plunge cut right down the seam of the two doors should do the trick.
It's not impossible, just makes you think a bit. Remember, Identify and Visualize.
