Mr. Greer. I knew that after I heard the second one, that is when I looked over my shoulder, and I was conscious that there was something wrong, because that is when I saw Governor Connally. And when I turned around again, to the best of my recollection there was another one, right immediately after.
Mr. Specter. To the best of your ability to recollect and estimate, how much time elapsed from the first noise which you have described as being similar to the backfire of a motor vehicle until you heard the second noise?
Mr. Greer. It seems a matter of seconds, I really couldn't say. Three or four seconds.
Mr. Specter. How much time elapsed, to the best of your ability to estimate and recollect, between the time of the second noise and the time of the third noise?
Mr. Greer. The last two seemed to be just simultaneously, one behind the other, but I don't recollect just how much, how many seconds were between the two. I couldn't really say.
Mr. Specter. Describe as best you can the types of sound of the second report, as distinguished from the first noise which you said was similar to a motorcycle backfire?
Mr. Greer. The second one didn't sound any different much than the first one but I kind of got, by turning around, I don't know whether I got a little concussion of it, maybe when it hit something or not, I may have gotten a little concussion that made me think there was something different to it. But so far as the noise is concerned, I haven't got any memory of any difference in them at all.
Mr. Specter. Describe as best you can the sound of the third noise.
Mr. Greer. Just, to me it was similar, to the first two. They all sounded practically the same to me.
Mr. Specter. You testified that at the second noise you glanced over your shoulder.
