To simulate this, they put some weights on the window of a car door held in a horizontal position... If you look closely at it, it seems pretty obvious that the weights window was cracking open up to the point where the weights started hitting the bottom edge of the window... I suspect that the results from water pressure being distributed across the face of the window would not act the same... At the very least, even the small amount that the window would open would allow the water to enter the vehicle quicker and as such equalize pressure quicker and thus allow you to open the door quicker... With regards to the cell phone usage aboard an aircraft, they also said that they were prevented from doing it in the air because FAA rules made it illegal... In fact, it is FCC rules and it is because of concerns of the phones contacting multiple cell phone towers at the same time... The way I understand it, the FAA rules concern airliners, so with regards to that, they could have made the test on a VFR flight without any FAA consequences... Now, this doesn't address the issue of whether you can even get a cell phone signal while in the air... My experience with Verizon is that above about 500 ft or so, if a signal is available, it doesn't last long enough for me to make a call... On the other hand, the old analog cell phones would work at 10K ft... Of course, this was back in the old bag phone days with a real handset, so you had to cut the engine back to idle slow down as much as possible to reduce the engine and wind noise so that you could actually hear what was said on the phone... Let's just say that it was not conducive towards long conversations... |

I seen the exact same thing last night. Why they just didn't submerge the car and let Jamie mess with it with his scuba gear on was a little dumb, it would have taken 2 minutes. ----------------------------------- DW |
