Official UFOs:

Conference on AERIAL PHENOMENA

Dr. Teller: Now let's try a check of this.

(Dr. Teller then spent approximately the next twenty minutes or so figuring out on the blackboard - estimating light, speed, kinetic energy, shock wave, etc.)

Dr. Teller: If I can just believe everything that I have heard and put it together with what I theoretically believe in, it ought to be a material body - might be an electron phenomenon.

Dr. LaPaz: You see why I'm puzzled, Dr. Teller. Nothing like this, to my knowledge, has ever been observed in the case of meteorite drops.

Dr. Teller: If you go to a group like UCLA or some other place where they have a good sound laboratory, they ought to be able to take the absence of sound observations - that is definitely incompatible, assuming that you know that there are ... and assuming that they have heard of no sound from this, they ought to be able to work an upper range upon the sight of the object which has been moving, and from these figures I would be inclined to believe the object could probably not have a heat? or something like 1 cubic centimeter. One centimeter in dimension, and that in turn would not have given the blinding effect, it [if] it was a material object.

Dr. Bradbury: Wait a minute, I think you've left out something in light effects - you don't have to worry about kinetic energy. You can get your light from chemicals as well.

Dr. Teller: That is correct ...

Mr. Newburger: This seems to wind up the meeting.

Dr. Bradbury: Still don't think that the meteor stuff is out. The puzzling thing is the long horizontal path; also absence of noise is puzzling.
