Shall we be rational here?

To do something, a person or organisation needs the ability to do so, the chance to, and the motive to.

We can assume that the USAF has the ability to convert a cargo aircraft into a 'vapor trail' laying aircraft.

We know, by waving the stick called national security, they can do almost anything they like.

We can assume that the USAF is reasonably sane, so they are not laying special clouds to stop Elvis landing. So why are they doing it?

1. The USAF is taking global warming seriously, and is trying to prevent it.
Odd, I though the Goverment was under the control of Exxon, so Global warming doesn't exist.

2. The Pentagon has no air conditioning, so this is to lower the temprature, and make up for this.
It's currently 61 F. Clearly far too hot.

3.Any other offers...

4. It really is just a new fuel mix.
