I found the "seeding" experimentation segment very interesting... they discussed some storm that did a 180 and went into Savannah, sort of reminded me of the 180 that Betsy took in 1965... there were rumors about it being a "seeding" experiment as well. The concept of both weather modification AND control was intriguing... and somewhat disturbing.

Yeah, some things are better left alone to ther own devices.... Right, wrong, or indifferent, nature needs to do what it is intended to do - otherwise things could become, as you said, "somewhat distrubing".

Discovery Communications, 1998 CHECK THIS OUT......
Kerry Emanuel describes the worst hurricane that could ever happen: Winds whip around its center at 500 miles an hour. Water vapor, sea spray and storm debris are catapulted into the atmosphere, punching a hole in the stratosphere 20 miles above the Earth's surface. If this meteorologist's nightmare ever made landfall, its super-gale-force winds would flatten forests and toss boulders. A 60-foot storm surge would flood nearby shores. The water vapor and debris could remain suspended high in the atmosphere for years, disrupting the climate and eating away at Earth's protective ozone layer.
Emanuel calls this a "hypercane."
Don't expect one to be brewing any time soon, however. These hurricanes from hell are a figment of Emanuel's computer models. A professor at MIT's atmosphere, oceans and climate program, Emanuel studies the physics of hurricanes, placing him among an elite group of scientists. He flies into these ferocious tropical storms and measures their physical properties. On land, he deconstructs their machinery using computer models, and digs into their geologic past -- all to understand what makes these whopper storms tick.
No one knows for sure how hurricanes get started. The ingredients for cooking one up still remain a mystery. A basic recipe: ocean water 80 degrees or warmer, super humid air, and a bunch of storms with thunderheads. Some assembly still required. "Hurricanes are accidents of nature," Emanuel says. "Even if all the conditions are right, and they often are in the tropical ocean, hurricanes don't happen by themselves. They literally need to be triggered."
Genesis is one of the great enigmas for those who study hurricanes. In 1991, Emanuel flew a research plane into some cloud clusters off the coast of Mexico to see which ones became hurricanes and which ones didn't. During those flights, Emanuel witnessed the birth of Hurricane Guillermo, a classic hurricane and one of the best studied pre-hurricanes.
Will we ever witness a hurricane as mighty as the ones depicted in Emanuel's computers? It's unlikely, even in the most dire global warming scenario, according to Emanuel. To create such a monster, parts of the ocean would have to warm up to at least 100 degrees. Only the impact of a large asteroid hitting the tropical ocean or a massive undersea volcano could generate such intense heating. It might have happened at least once in our past, though. Emanuel and his colleagues theorize that asteroid-triggered hypercanes may have contributed to massive global extinctions millions of years ago.
In our present climate, the worst possible hurricane would have winds of 200 mph. Thankfully most cyclones don't live up to that potential, although Hurricane Andrew came close. By the time it hit Florida in August 1992, it had sustained winds of 145 mph. When at sea, Andrew barely made it to hurricane status, which is defined by a wind speed of 74 mph or greater. Within a day or two, its intensity had shot up. It surprised everyone

I love the quote they just said on the show..."Ivan's winds revved up to 130mph". That is really funny because Ivan only made landfall at 120mph and in Pensacola the highest gusts were only near 105-115mph (may be 115-120mph at the coast).

Interesting for comparison in shape/structure; but little more, that Giant Red Spot is twice the size of planet Earth--and it's been around for centuries...
But as you're watching the same documentary I am, I'm sure you already knew that

They could've been referring to gusts; not to mention, not all sources use the "official" NHC report as the ultimate word... although in essence I concur with your statement. They stretched a lot of things, including the previously alluded to Hypercanes to which some are now attributing the demise of the dinosaurs... oh well, another theory in the stew.

Did you see the guy who would go out in the water, to film hurricane waves coming in!! 
I like viewing extreme weather as much as the next guy; but that seems just a tad over the edge!
