Jeanne,
That's to say that there aren't airports or military bases within about 45 minutes of flying range. By using the average cruising flight speed for commercial jets of around 540 mph, a plan can go 405 miles within 45 minutes. That doesn't even include wind currents. Don't get me wrong, I'm not saying, nor can I prove, that chem trails aren't what conspiracy theorists are saying. I tend to lean more toward the most simplest of answers. I am willing to be corrected if reasonable evidence occurs. And like I've said, jet fuel has been found in women's breast milk. Rocket fuel has also been detected. So regardless, it's obvious that something needs to be done. But I can see how this problem can be a benefit to the "medical field" or to pharmaceutical companies.
