eric3579You probably saw the other videos he had done on YouTube and Twiter manipulation, but in case you hadn't...

Terrifying RC Helicopter Breaks Reality
LiquidDrift says...Oh ya it's totally real. Smarter Every Day did a pretty cool series on helicopter physics that's worth checking out:

There are many pilots that can do the tricks in this video, but Tareq Alsaadi is world class and I haven't seen anyone else do this between trees much less in the dark. He's beyond wizard, into demon territory.
I was going to call 'fake' but his instagram is full of videos like this.
I had no idea that the laws of physics had no grasp on RC choppers.
Because the window will stop him...

Most vehicle side windows are made of tempered glass, compared to the laminated glass of the windscreen. The windshield is designed to "hold" its pieces upon severe impact due to the lamination process (a layer of plastic material sandwiched between two layers of glass) whereas the tempered side windows will shatter into small relatively harmless globules. Tempered glass is used due to it being roughly 4x the strength of non tempered glass, and cheaper to produce than laminated.
Most automotive side glass is typically between 3-6mm thick, depending on the region of origin, eg Europe, Japan, USA etc. That said, calculating the compression, tensile and sheer strength a particular window can sustain is not exactly simple. However as a simple baseline, a 2ftx2ftx5mm sheet of tempered glass, with supports 2ft apart can support roughly 160lbs of sustained weight. In the case of automotive design, window frame support, distance of supports, curvature etc will change the properties and strength of the glass.
Long story short, with the vehicles window fully rolled into the frame, that lion would need hundreds of pounds of force directed at a single point to reach the shatter point. Granted, I've never arm wrestled a lion, so maybe those folks were just a can of Vienna Sausage ready to open anyway. Best not to mess with the king.
