Wecht responds it s all about the bullet's trajectories; the men's reactions don't make any difference.
Representative HAROLD E. FORD asks if Wecht privy to any other evidence that panel wouldn't have seen - Wecht responds no other than a blow up of the Zapruder film at Life magazine headquarters.
Representative MCKINNEY asks of the Zapruder film, the bullet trajectories, and the condition of the bullet which is the most significant to Wecht's disagreement with the single bullet theory - Wecht responds the trajectories would be first, followed by the condition of bullet, followed by the film - but adds that they are all integrated in his analysis.
McKinney confirms that based on the men's positioning in the Zapruder film that it is Wecht's opinion that the bullet's trajectories are impossible - Wecht says he has never heard any testimony of dramatic movement on the men's part to get them lined up so as to make the bullet's path possible.
Fithian asks if evidence becomes available that the fragments in Connally s wrist came from bullet 399 wouldn't this impair Wecht's interpretation - Wecht says test would have to be conducted on all bullet fragments for him to be swayed and other trajectory and damage tests would have to be conducted.
Fithian wants to know if analysis of film and other techniques of Wecht on which he bases his interpretation fall outside of the field of forensic pathology - Wecht responds no and explains that these are legitimate techniques of the field.
Representative HAROLD S. SAWYER asks what happened to the other bullet if there was more than two fired and then asks where this bullet would have been fired from - Wecht answers possibly from a lower floor of the book depository.
Sawyer says he's seen studies that show erratic behavior of bullets when hit twigs. Wecht's response cut off by end of tape.
Opens to Representative FLOYD FITHIAN questioning witness H.B. McCLAIN, Dallas Police motorcycle man, Fithian asks McClain if he saw any activity around the grassy knoll - McClain responds that he saw Officer HARGAS (?) going up the knoll
Dodd asks McClain if the dispatch radio at headquarters could receive two transmissions at once - McClain responds that it would happen often, mixing the transmissions together - Dodd asks McClain if he knew of any bell noises emanating from Dealey Plaza - McClain answers no.
Stokes recognizes McClain's opportunity to supplement his testimony - McClain declines to do so - Stokes calls a recess.
Hearings host PAUL DUKE voices over shot of hearing room with summary of the morning's testimony. Shot changes to Duke in broadcast booth, he introduces his panel CARL OGLESBY of the Assassination Information Bureau and JEREMIAH O'LEARY of the Washington Star who discusses the day's testimony thus far. Duke closes out the morning's coverage.
Shot returns to hearing room.

Shot opens up to hearing room, Duke voices over an introduction to the afternoon's hearings, shot soon after switches to him, he goes on to sum up the morning's testimony. Duke again introduces panel, Oglesby and O'Leary, who discuss the conspiracy implications of the morning's testimony.
Duke introduces to the Committee Vice Chairman Representative RICHARDSON PREYER, Duke, Preyer and O'Leary have a long discussion about the morning's testimony, Preyer says he believes it pretty definitively implicates a second shooter and therefore a conspiracy, but he believes this conspiracy not to be planned by any large political organization, rather he suggests it was a conspiracy of "nuts", Preyer also defends the conclusions of the morning's witnesses, E. ASCHKENASY and MARK WEISS, against attacks O'Leary launches against them saying they made huge assumptions and produced results applicable only to laboratory conditions.
Duke introduces the afternoon's testimony and shot returns to hearings room.
Chairman Stokes recognizes Chief Counsel Professor ROBERT BLAKEY, Blakey begins by siting evidence that substantiate the temperature at Dealey Plaza at the time of the assassination (an issue that came up in the morning testimony of Aschkenasy and Weiss), Blakey then goes on to introduce Dr. ROBERT BARGER and list his credentials
Stokes calls and swears in Barger and recognizes Deputy Chief Counsel JAMES WOLF, Wolf confirms Barger's accomplishment at the Kent State trial, then asks a bit of background about his original testimony before the committee in May ('78).
Wolf reviews with Barger the acoustic research experiments he conducted in August in Dealey Plaza using an exhibit of a survey map of Dealey plaza, on the map Barger points out the markers which indicate his equipment positioning, namely microphones and rifle firing locations.
Wolf introduces an exhibit of a chart of 4 groupings of impulses and their corresponding measurements that Barger believes are gun shots, Barger then explains at length how these groupings or fingerprints as he calls them (the sound waves produced by each of the gun shots Barger describes as a unique fingerprint) correspond to the sound waves recorded by microphones Barger had lining the roads around Dealey plaza.
Wolf has Barger explain his markings on the map which indicates the position of the motorcycle (and recording) relative to the microphones he set up - Wolf also confirms that Barger's locations of the motorcycle match those recalled by McClain - Barger confirms this with a long explanation.
Wolf quotes from a report of another scientist's acoustic analysis of the tape that suggests, based on the crescendo and decrescendo of the siren volume, that the motorcycle recording came from a motorcycle that was not part of the motorcade - Barger rejects this challenge by saying that the siren noise level would been softer in volume than that of the ambient noise entering the microphone.
Wolf quotes again from the above mentioned report, this time it is a section which mentions that the tape also has a bell noise on it and points out the location of a likely candidate to have produced such a noise, the location of this bell is not close to Dealey Plaza - Barger says that he agrees with McClain's earlier testimony that Police dispatch radio will merge simultaneous transmissions from different radios and that anyway the bell noise occurs after what he has identified as the four shots.
