I'm here at the Regalo kite festival here in Kitty Hawk, North Carolina 00:00:00
People from all over the world come here to fly their kites on the same sand dunes that the Wright brothers used to fly the 00:00:04
Very first airplane now. Did you know that the Chinese were the first people to fly kites? 00:00:10
Almost 3,000 years ago the Chinese built kites out of silk and bamboo 00:00:15
For years the kite has been thought of as a trivial toy 00:00:19
But history tells us that the kite is so much more than a toy 00:00:22
Throughout history kites have been used by civil engineers to construct bridges and perhaps most famously by Ben Franklin to study electricity 00:00:26
Why even NASA has studied kites matter of fact this kite festival is named for a famous NASA researcher and his work with the 00:00:34
flexible wing 00:00:42
Mr. Francis Regalo known as the father of hang gliding created the paraglider 00:00:43
That was one of the possible design solutions for returning a space capsule back to earth 00:00:47
Mr. Regalo is here today for this kite festival. He has given me some background on how a flexible wing works 00:00:53
Want to know more visit the NASA Connect website 00:00:59
And they know van if you'd like to fly we can go out there and go hang gliding. Oh, wow, that'd be great 00:01:04
Yeah, right now right now. All right. Let's go 00:01:11
We'll be back in just a few moments to catch up with van, but right now we're here at windy, Manteo, North Carolina 00:01:16
Actually, we're at the Deer County Airport where Air Venture 98 is just about ready to get underway Air Venture 98 00:01:21
Now that's an air race for experimental aircraft, but not too far from here is Kitty Hawk 00:01:27
Which is the site of the first historic powered air flight in 1903 00:01:32
The Wright brothers changed the world forever when Orville Wright went up into the air for the first successful heavier-than-air flight 00:01:37
This machine was just one step in a broad experimental program that began with a glider kite that they built in 1899 00:01:43
Not only did they build the first successful plane 00:01:50
But they built the first wind tunnel and they had to find out for themselves the dynamics of lift 00:01:52
drag 00:01:58
weight and thrust on a shape 00:01:59
Ever since the Wright brothers successfully tested their flying machine off the sand dunes of Kitty Hawk 00:02:03
We've seen a multitude of designers, builders, and inventors trying to take their machines to some place faster, farther, and higher 00:02:08
Well, that's what Air Venture 98 is all about. It honors those people 00:02:15
They will set off right here from historic, North Carolina and set sail across the skies to Oshkosh, Wisconsin 00:02:19
Where they're set to kick off the largest experimental aircraft air show in North America, Oshkosh 00:02:26
Aviation enthusiasts annually gather in Oshkosh to witness first-hand new design concepts and technologies that could open up new vistas to the field of aeronautical engineering and to personal and commercial aircraft venues 00:02:32
Air Venture brings out many different personalities and many different extraordinary looking aircraft 00:02:45
Joining me right now is a very special personality, Hoot Gibson, who is a former astronaut, was a commander of the U.S. Air Force 00:02:50
Joining me right now is a very special personality, Hoot Gibson, who is a former astronaut, was a commander on four missions, and has flown over 60 different airplanes 00:02:56
And behind me you can see the airplane he's going to be racing in 00:03:06
How about giving us a little lowdown on this big plane? 00:03:09
Well, Shelley, this airplane is a Hawker Sea Fury built by the British right after World War II 00:03:12
So right in the late 40s and early 50s is when these airplanes started flying 00:03:18
It's a really interesting bird 00:03:22
It's a very big, heavy, powerful machine 00:03:24
It weighs about 9,000 pounds 00:03:26
It has a 3,000 horsepower engine in it 00:03:29
And as you can see, it's got about a 14-foot diameter propeller 00:03:32
As you can see, the wings fold, of course 00:03:36
It used to be a carrier fighter, was what the British used it for 00:03:39
And you always want to minimize the size of the airplane when it's time to stow it away on the carrier 00:03:42
So you fold the wings and it takes up a lot less space 00:03:48
The wings actually cost you a little bit of weight 00:03:51
Because you've got to put in some mechanism to make the wings fold and to lock the wings 00:03:54
Because, of course, you want to lock them when they're down 00:03:58
You don't want them folding up by themselves, obviously 00:04:01
Yeah, well, I have a final question for you 00:04:03
This is what I call a tortoise and hare question 00:04:05
Your plane certainly is bigger than any other airplane that's going to be in this air race 00:04:08
So, given that, which plane do you think is going to be your closest competitor in this race? 00:04:13
I'm not even sure, Shelley, that we're going to win this race 00:04:19
We do have the biggest, most powerful, heaviest airplane out here 00:04:22
But it doesn't have any kind of guarantee that we're going to win 00:04:26
The other airplane that I think is real fast and may be a real problem for us is the Lancer 4 00:04:29
With the Chevrolet V8 engine in it, with the five-bladed propeller 00:04:35
I think he's going to be very fast 00:04:39
And he's going to fly a lot higher 00:04:41
He can be up in the 25,000 to 30,000-foot range 00:04:43
We're going to be quite a bit lower 00:04:48
We're going to be down around 20,000 feet, somewhere around there 00:04:49
So he's going to be some real competition, I think, on this length of a race 00:04:52
So there's a lot of variables in here that are going to enter into this race 00:04:56
There really are 00:04:59
So stay tuned. We'll see who comes out ahead 00:05:00
