Gov. John Connally Grips His White Stetson Hat at Z-272

[Andrew Mason]

If the "second had not completely died out before the third shot sounded" that could not possibly be two shots from Oswald's rifle. You keep arguing for things that are impossible.

If you know how long a rifle shot in Dealey Plaza would have persisted, then you should provide it along with the source.

There was a large post office building a bit more than 600 feet (188 m measured on Google maps, which is 616 feet) directly south of the TSBD. There were also buildings on the east side over that distance, pavement and concrete structures in Dealey Plaza. There was also the triple underpass about 500-550 feet south west of the SN as well as a railway embankment all along the west side. There were also reflective surfaces in between the TSBD and the underpass. So it was a real reverberation chamber:
. 

Sound from the 6th floor TSBD would have reflected off all those surfaces and then back to the people standing on the north side of Elm St. where Mary Woodward was.  The sound wave front would have taken a tad more than half a second: .55 seconds (speed of sound at 68F is 1127 fps) to directly reach the Post Office building and a bit more for sound waves reflected from the street, buildings along Houston and other concrete structures.  The sound then would have bounced back off the Post Office building as well as back off the triple underpass and arrived at the ears of Mary Woodward.  So she would definitely have heard the first round of continuous echos (reverberation) for at least 1.2 seconds after the blast.

But the reverberation doesn't just end on that first reflection.  It would have gone back and forth a bit. The reverberations from the first reflection back off the TSBD would have traveled south toward the Post Office building and bounced again of that large surface, arriving at Mary Woodward over the next 1.2 seconds. Same with the sound reflecting from the triple underpass back off the building along Houston and structures in between, although with a bit less travel time.

So unless the sound reflected only one time before ending completely, the reverberations could easily have continued for about 2.4 seconds.

Mary Woodward said that there was a third shot within the period of reverberation of the second shot.  She recalled three distinct shots.  She said she would go to her grave swearing that there were three shots. See this Youtube clip. Her statement begins about 2:50.

If you are going to postulate that the sound of a single shot could reverberate for 2 seconds or more, the burden is on you to prove that.

Wouldn't it be easier just to scrap your silly theory and start over than to keep coming up with ever more ridiculous explanations. I'm still waiting for you to explain how Oswald shot JBC in the back at a time JBC had spun around and was facing him.
