Hi GSXR1000 ,
I got the same Email yesterday and I got a good chuckle out of the "Unless the operator has received specific authorization from the administrator of the FAA to conduct the operation" language .
I'll bet the FAA gets a few Emails like ;
"Hey , yo Mr. FAA dude , I wanna hang a huge effin gun on my drone so I can thrash Bubba's flamethrower drone , U down wit dat ?"
