It shattered the front door (glass). Did not break the big windows on the west side of the station. When I passed it, I thought someone had simply broken the door with a crobar or something.

As I understand it, the door and the window were damaged. One report stated that the door frame was damaged. (I believe I read that...)

If this is the case, it would seem to me that a stick of dynamite or so would have to been required.

It does depend on the placement of the divice. If it was thrown on the sidewalk, it would require more explosive than it would if it were taped to the door.

I don’t consider something of that level to be a minor explosion. People felt this blast over a block away.

From the NY GOE website:

From the photographs and video it is obvious that this was not the work of kids playing with firecrackers. The safety glass windows are shattered. The steel door is sprung from its hinges. The large video screen above the entrance is damaged. Witnesses on the 21st floor report feeling the building shake at the Marriott Hotel two blocks away.

Pictures look like more than a shattered glass and crowbar damage to the door...
