I believe the box of truth is a fair and unbiased authority on many subjects, including this one.
2How, I don't know about the BoT in general, but I agree with you on this point... I just confirmed that their site DOES NOT
support the statement made in your initial post...... the bullet is not going to always go high... it is likely to follow the rule of moving towards a 90 degree angle from the far surface of the glass (high when firing out of a windshield, low when firing into a car through the windshield... as demonstrated in their tests, via the link you provided).
I was correcting this mis-statement:
.... the bullet will be several inches high when exiting and the same when entering.
Keep in mind that under I.C.E., we always look for the WHY?
.... we aren't interested in the "what" alone... so when I see an empirical test as they ran at BoT, there needs to be an follow up question: Why does that happen? Obviously, in this case, it is because the first contact the round has with the glass is going to "pull" the bullet in the direction of the glass, which initiates a tumble, might cause the bullet to start breaking apart and results in a new direction of travel closer to the 90 degrees from the far side surface....
The hood phenomenon is why we recommend going "around" cover whenever possible as opposed to going over... skips off a flat surface pose a serious and sometimes unpredictable threat.
The likely reason for the lack of significant deflection was the proximity of the target to the glass.... distance magnifies the effect of deviation/deflection, but if the balloon is only one foot from the windshield, there won't be much noticeable effect.
Perhaps that was not what you meant to say.... either way, I just wanted to make sure those coming here for accurate info were not mis-directed.
We've done that too (shot up engines).... and the fact is that is really has a lot to more to do with what is struck than what you fire into the car... much like a human body! Is a .50 BMG more likely to disable a vehicle? Of course..... but a 9mm round into the radiator could cause enough damage to stop the car eventually as well..... same for a .22 that cuts an important belt or pierces the transmission fluid radiator present on many vehicles.
