1
00:00:00,000 --> 00:00:05,000
Slow down there, son. Be careful.

2
00:00:05,000 --> 00:00:07,000
Sorry. I guess I just got carried away when I saw you.

3
00:00:07,000 --> 00:00:09,000
You're Wobble Wright, aren't you?

4
00:00:09,000 --> 00:00:11,000
What are you doing here?

5
00:00:11,000 --> 00:00:13,000
We're hoping to test our new glider.

6
00:00:13,000 --> 00:00:15,000
If our weather conditions improve.

7
00:00:15,000 --> 00:00:17,000
Last year was very frustrating for us.

8
00:00:17,000 --> 00:00:19,000
It was a failure, Wobble.

9
00:00:19,000 --> 00:00:22,000
We'd been using Otto Lilienthal's lift calculations,

10
00:00:22,000 --> 00:00:24,000
which were generally considered to be accurate.

11
00:00:24,000 --> 00:00:26,000
But after last year's frustrations,

12
00:00:26,000 --> 00:00:28,000
we wondered if they might be wrong.

13
00:00:28,000 --> 00:00:30,000
So we decided to do our own lift calculations.

14
00:00:30,000 --> 00:00:32,000
How did you do that?

15
00:00:32,000 --> 00:00:34,000
Wobble built a wind tunnel

16
00:00:34,000 --> 00:00:37,000
and created a wonderful scale to measure and calculate lift.

17
00:00:37,000 --> 00:00:40,000
We created and tested several different types of airfoils

18
00:00:40,000 --> 00:00:42,000
to find the one with the most lift.

19
00:00:42,000 --> 00:00:44,000
We're really anxious to test it

20
00:00:44,000 --> 00:00:46,000
as soon as the wind conditions are favorable.

21
00:00:46,000 --> 00:00:48,000
Why can't you test them now?

22
00:00:48,000 --> 00:00:50,000
How can you stand waiting?

23
00:00:50,000 --> 00:00:52,000
Waiting is difficult.

24
00:00:52,000 --> 00:00:54,000
But if we don't conduct our tests in appropriate conditions,

25
00:00:54,000 --> 00:00:56,000
we might invalidate our results.

26
00:00:56,000 --> 00:00:58,000
Worse yet, we could damage our glider

27
00:00:58,000 --> 00:01:00,000
and ourselves.

28
00:01:00,000 --> 00:01:02,000
No, we must wait until conditions are right.
