Slow down there, son. Be careful. 00:00:00
Sorry. I guess I just got carried away when I saw you. 00:00:05
You're Wobble Wright, aren't you? 00:00:07
What are you doing here? 00:00:09
We're hoping to test our new glider. 00:00:11
If our weather conditions improve. 00:00:13
Last year was very frustrating for us. 00:00:15
It was a failure, Wobble. 00:00:17
We'd been using Otto Lilienthal's lift calculations, 00:00:19
which were generally considered to be accurate. 00:00:22
But after last year's frustrations, 00:00:24
we wondered if they might be wrong. 00:00:26
So we decided to do our own lift calculations. 00:00:28
How did you do that? 00:00:30
Wobble built a wind tunnel 00:00:32
and created a wonderful scale to measure and calculate lift. 00:00:34
We created and tested several different types of airfoils 00:00:37
to find the one with the most lift. 00:00:40
We're really anxious to test it 00:00:42
as soon as the wind conditions are favorable. 00:00:44
Why can't you test them now? 00:00:46
How can you stand waiting? 00:00:48
Waiting is difficult. 00:00:50
But if we don't conduct our tests in appropriate conditions, 00:00:52
we might invalidate our results. 00:00:54
Worse yet, we could damage our glider 00:00:56
and ourselves. 00:00:58
No, we must wait until conditions are right. 00:01:00
