that doesn't appear to me to be the same thing as the multiple planes doing the crisscross patterns. this thread is long and i haven't read it all, but has anyone explained the difference between one plane with a con? chem? trail behind it as opposed to 2 and sometimes 3 crisscrossing over the same area for hours?
something else that ought to be mentioned, especially if you live in central texas: texas is infested with military flight schools.
very few people are "natural" pilots... most pilots have to be trained in formation flying, combat tactics and manuevers, instrument approaches, everything...
for instance, if you're practicing instrument approaches, you will practice at high altitude so you dont gum the works up for people who actually want to land at the airport you're practicing on... not to mention that jets get lots better mileage at high altitudes.
all this training activity can result in otherwise nonsensical-appearing flight patterns and contrails.
See christine, you apparently never noticed all those trails in the sky till you read about it on the Internet, and groundresonance just taught you about what your sky looks like, with all those jets flying at high altitudes, even though the chemtrails you're seeing are probably at 10,000 feet or less...
