A "take shelter" drill-- Israeli style

Today all schools around Tel Aviv, there was a "take shelter" drill.
In the States, these days, that drill is for hurricanes or tornadoes. Here, in Israel, we practice taking shelter from bombs. The kids don't go into a window-less room or hallway and kneel & cover their heads with their hands. They go into a bomb shelter. I think this might have been the first one they've done this year, but that still doesn't explain the mass chaos that took place during this drill. With the exception of the 1st graders, they've all done it at least once before.
In the States, drills are taken seriously, like the emergency is actually happening. The kids are quiet, listening for instructions, walking from place to place, albeit quickly. In Israel, kids/people don't have quite the same respect for order or authority. (Apparently this is supposed to change when they go into the army, but it seems that they forget all their respect & order training within 10 years afterward.)
2nd period was cut short so that the kids could have recess before the drill. When the bell rang, the kids were supposed to go back to their rooms and get under their desks, for about 5 minutes, until the siren sounded. 2 6th graders with a roll list were "in charge" of each class and met the teacher in the room. Seriously, I directed my questions about what was happening to them because they knew more than my cooperating teacher. This under the desk business just meant play time to the kids. They didn't get quiet longer than 30 seconds for anyone asking for it. They were partially under, partially under, no kneeling, just hanging out. A few even got up & switched spots to go be with their friends.
When the siren sounded, we waited 2 minutes to let the other hallway go down the stairs first so it wouldn't get too congested, as if in a real emergency we wouldn't use the other stairwell that was only slightly farther away from the bomb shelter. When we left, I looked out the hallway window and saw herds of kids full speed running across the school yard to the shelter. No order, no sight of any teachers, who were most likely, walking slowly behind, talking to each other. When we got to the stairs, the class in front has been stopped for whatever reason. This was as far as we got and even the 6th graders "in charge" had no idea why. We sat the kids on the stairs and waited 10 minutes until it was over. The noise from the 2 classes was deafening. I actually covered my ears as I sat at the top of the stairs and they were still ringing for a while after. At least my cooperating teacher thought this whole situation was as ridiculous as I did. As we sat there, she turned to me and said, "As if the roof won't fall in if there's a real bomb?"
I wouldn't say I'm still experiencing culture shock, but I am occasionally still shocked by this culture.
