| Description: | (02:02:40) Opens to discussion between E. ASCHKENASY, MARK WEISS, and Representative FLOYD FITHIAN about the acoustic tests and evidence used in these tests (02:03:48) Committee Chairman LOUIS STOKES recognizes Representative ROBERT EDGAR, Edgar says that his questions will be of a more technical nature as he is representing his and the questions of various scientists and legal experts who have all reviewed earlier testimony and reports of Weiss and Aschkenasy, Edgar's first question is how much of a factor was temperature in the experiments of Weiss and Aschkenasy - Weiss explains how they took it into account in their analysis (02:07:56) Edgar asks if the temperature during the assassination would have effected the speed at which the sound waves traveled - Asckenasy responds that its effect would have been insignificant because of the short distance and time in which the sound waves traveled and echoed (02:12:30) Stokes asks whether Weiss and Aschkenasy can determine the trajectory of the bullet - Weiss responds that the data they analyzed provides no more information on this other than the fact that the microphone picked up a shock wave meaning the gun fired from the knoll would have been in the general direction of the motorcade (02:15:06) Stokes recognizes Representative RICHARDSON PREYER, Preyer asks how Weiss and Aschkenasy accounted for the fact that the police tape of the assassination was recorded at a 5% slower speed than it happened in real-life - Weiss explains how they factored this into their analysis (02:19:35) Preyer asks about the use of new technologies to eliminate from the tape low level noises - Weiss says that they did not do this in their analysis (02:20:49) Stokes recognizes Representative SAMUEL DEVINE, Devine confirms that in sinking the tape to the Zapruder film one would have to take into account the fact that the shot was traveling at a super sonic speed and therefore would have likely hit its target before the sound was heard, he then asks Weiss if different experts can interpret facts differently - Weiss responds that this is true only if there is room within the facts for different interpretations (02:23:16) Stokes recognizes Delegate WALTER FAUNTROY, Fauntroy cofirms new technology or methods that have not undergone scientific scrutiny were not used in reaching Weiss and Aschkenasy's conclusions, Fauntroy then asks the Committee where they got their temperature figure for that day in Dallas (02:24:10) Blakey gives the committee the source of the temperature, Blakey then asks if one knows all the factors that the committee has come to about the three other shots fired by Oswald, their velocity, trajectory and points of impact could one then determine the temperature from this - Weiss seems disturbed by the proposition, he says it is possible to do but would involve a lot of new calculations and take some time (02:26:38) Fauntroy confirms that Aschkenasy and Weiss could calculate the temperature from the above given information - Weiss says they could do it but goes on to stress the relative insignificance of the temperature in their calculations (02:28:54) Edgar jumps in with another temperature question which Weiss and Asckenasy fend off (02:30:47) Stokes recognizes Representative CHRISTOPHER DODD who asks first about discrepancies between the map used in the men's calculations, Dodd then asks if a recreation with a motorcycle, gun shot and microphone would help substantiate things - Weiss responds that such a recreation would only give you a very similar echo structure to the one Weiss and Aschkenasy produced - Dodd then asks about the effect of moving the concluded location of the grassy knoll shooter - Weiss' response is cut short by the end of the tape | |
