During an international Air Canada flight, they had USB ports right beside the touch screen seat back monitors. I thought I'd try plugging my remote mouse into it. Worked perfectly fine, a mouse pointer showed up and I could use it fine.
I was wondering what I could do with a keyboard, or a nicely crafted USB stick. The interface seems to be an HTML/JS interface, so I'm not sure what OS it was running on. The mouse pointer was not a Windows default so it was probably Linux.
I wonder if I could have switched terminals if I had my keyboard. Also, if I had my keyboard I'd be too scared to try.
