Yes, yes I know.  You're all safe and cozy because they checked your shoes and shorts.  They made sure that the babies diapers weren't full of anything too explosive.  They made grandma give up her hand lotion because it was 3.5 ounces.

But you have to wonder.  If a kid, yes a kid who was only 15 years old was able to hide in the wheel well of a transoceanic flight and escape detection by the ever vigilant TSA agents then how hard would it be to hide a device in that wheel well?  

Looks like you're giving up your freedom and dignity for naught.
