Mr. Specter. And had you maintained the distance which you have described heretofore behind the President's followup car?
Mr. Youngblood. Yes, generally. Sometimes as we went around corners, we tried to close up the gap a little bit. But as soon as we got on a straight stretch, we would drop back two or three car lengths.
Mr. Specter. Well, at this particular time, what is your best recollection of the distance between the Presidential followup car and the Vice President's car?
Mr. Youngblood. We are on Elm Street now.
Mr. Specter. At the time the first shot occurred.
Mr. Youngblood. We were two or three car lengths behind.
Mr. Specter. And how far behind the President's car was the Presidential followup car at the time of the first shot?
Mr. Youngblood. I would think somewhat less than a car length.
Mr. Specter. What is your best estimate of the total timespan between the first and third shots which you have already described?
