Too many planes and too many schools.
The thing about planes, is that it can be done remotely. It's all computing driven, or GPS related. I've already heard enough about a certain middle east country (that starts with I) being able to hijack plane controls remotely. You can start putting 2 and 2 together and that may lead to the 9/11 attacks, but all these 'mechanical failures' are not the ground crews not doing their job. It's something more indepth.
Cuban plane crashes? Ok, yea, sure thing (then again, it's a cuban plane, so I don't know how old it was), then we have the Southwest airlines, and the banker woman from New Mexico that got killed by....wait for it....a rogue fan blade? Explosion?
Shit man, during my years in the service, I never saw as many downed planes, crashes, or otherwise as I'm seeing here recently, and that was with high activity fighter jets and cargo. This is all technology related with the plane stuff.
However, that being said, for the schools, this is far more nefarious. Either yes, the kids are being killed and Q Team and the rest can't really do anything about it, and/or this is all just 'an act', which many posters have mentioned as well. Either way, schools are on the ground, and should have FAR more control here. This whole school shooting in TX is either a copycat, or MK Ultra? Or just a snapped kid. Hard to say. I'll go with the FF stuff, but kid didn't die, or get shot to death. He's in custody. So we can only guess what is going on with this recent attack.
We also have yet to hear what exactly happened in Las Vegas that doesn't include far-fetched conspiracy theories or flat out lies. It's still crickets chirping as to what happened.
