As soon as you've gone by it once, maybe missed it once, the next time you come through, you can give it up there at 10° if you want. You know exactly what you're looking for and you know what's coming before and you go right up to it and get a . . . Cause you're saying about 30 to do that or 45 down from the horizon for terrain and perhaps a little further up for weather. . . . 10° further up for weather on a first-on a chance basis target of opportunity. I just wanted to ask you that in your - part II of this - under the great and under the terrial - what is the ground altitude that you took 4 shots with the pitch down - I don't know if both of you were up or not. You pitched down and you fired a thruster as a preliminary to the experiment on the rediacal light to see how much the thruster flame would and could interfere with the target. I was just wondering what you actually observed on the . . . . . . Any brightness of the thruster and so forth and if it could have any effect on the target. I haven't found a photograph yet. Well on something like, you'd better really get over there and look for them because they're going to turn out black and your polaroid probably isn't going to print them.
