{SPEAKER name="KARL HEIMBURG"}
—and you had to have a jet deflector.

[00:03:22]
{SPEAKER name="KARL HEIMBURG"}
It was not as in Lehesten, you had a natural wall, a perpendicular wall.

[00:03:28]
{SPEAKER name="KARL HEIMBURG"}
You had to have a jet deflector, and on the other hand, in order to protect it from bomb raids, they had a heavy concrete layer on top of that tower.

{SPEAKER name="MICHAEL NEUFELD"}
Mmhmm.

[00:03:44]
{SPEAKER name="KARL HEIMBURG"}
Now you had two test stands inside and the--

[00:03:54]
{SPEAKER name="KARL HEIMBURG"}
--you have to see it this way.

[00:03:56]
{SPEAKER name="MICHAEL NEUFELD"}
Could you describe that visually?

[00:03:58]
{SPEAKER name="KARL HEIMBURG"}
Yeah. In the middle is the room from where you direct each test, to the left and the right.

[00:04:05]
{SPEAKER name="KARL HEIMBURG"}
You had a concrete wall separating you from the test tank, but you were very close by.

[00:04:11]
{SPEAKER name="KARL HEIMBURG"}
But you had the concrete wall and you had a double window, so that the noise was not too, uh, damaging to you, too damaging to your ears.

{SPEAKER name="MICHAEL NEUFELD"}
Mmhmm.

[00:04:23]
{SPEAKER name="KARL HEIMBURG"}
And uh, you had, then, the containers sitting on scales, for the--for the oxidizer and for the fuel.

[00:04:36]
{SPEAKER name="KARL HEIMBURG"}
Uh, so that you knew how much fuel did you use and how much oxidant did you use during the test.

[00:04:44]
{SPEAKER name="KARL HEIMBURG"}
And you could see your containers is, on account of the scale, getting empty.

[00:04:51]
{SPEAKER name="KARL HEIMBURG"}
Now I have to tell you something about that scale.

[00:04:55]
{SPEAKER name="KARL HEIMBURG"}
When I arrived there, uh, the container, on account of the vibration by the test, as it was close by, had shifted slightly against the wall.

[00:05:09]
{SPEAKER name="KARL HEIMBURG"}
And then of course, made the scale worthless.

[00:05:13]
{SPEAKER name="KARL HEIMBURG"}
This was ONE thing which they had not watched.

[00:05:17]
{SPEAKER name="KARL HEIMBURG"}
And on the other hand, when you pressurize your container and you, the scale—

[00:05:28]
{SPEAKER name="KARL HEIMBURG"}
—let me say: when you fuel your container and your scale is not working properly—
