That is not really true. They have 11 friends and family who saw it with their “Spiritual Eyes”
Now Tom, this is not true and you know it. Lets look at John Whitmer, one of the 11 witnesses to the book of mormon shall we? Here is John Whitmer:
There are two notable times that John Whitmer defended his testimony of seeing the plates, after leaving the church. The first was on April 5, 1835, when he was accompanying 8 of a group of 50 men who had sworn to not eat or drink until they had murdered “Joe” Smith. In other words, he was with a bunch of guys slightly hostile to the church. The 8 of them approached Theodore Turley, an elder in the church. They handed Elder Turley a revelation of Joseph Smith’s that they were convinced would never happen. They taunted him claiming this was proof that Joseph was a false prophet and demanded that he denounce the church once the revelation had passed without fulfillment. Turley scoffed at them defending the revelation then turned to John Whitmer and said,
“There are many things published that they say are true, and again turn around and say they are false?" Whitmer, asked, “Do you hint at me?” Elder Turley said, “If the cap fits you, wear it; all I know is that you have published to the world that an angel did present those plates to Joseph Smith.”
John replied: “I now say, I handled those plates; there were fine engravings on both sides. I handled them.” Then he described in the presence of these bitter enemies how the plates were fastened and he said, "They were shown to me by a supernatural power."
That was a pretty gutsy response considering he was associating with people who were out for violence against Joseph Smith and the Mormons. Incidentally, the revelation did happen when and where it was said to have. But that’s a subject for a whole other webpage.
The 2nd account came from what was probably John Whitmer’s final interview before his death. It’s funny how all these witnesses who leave the church keep reaffirming their testimonies on their deathbed. What does that tell you? Anyway, this Q&A was published a few weeks after John’s death.
Q - I am aware that your name is affixed to the testimony in the Book of Mormon that you saw the plates?
A - It is so, and that testimony is true.
Q - Did you handle the plates with your hands?
A - I did so!
Q - Then they were a material substance?
A - Yes, as material as anything can be.
Q - Were they heavy to lift?
A - Yes, and as you know gold is a heavy metal: they were very heavy.
Q - How big were the leaves?
A - So far as I recollect, 8 by 6 or seven inches.
Q - Were the leaves thick?
A - Yes, just so thick, that characters could be engraven on both sides.
Q - How were the leaves joined together?
A - In three rings, each one in the shape of a D with the straight line towards the center.
Q - In what place did you see the plates?
A - In Joseph Smith’s house; he had them there.
Q - Did you see them covered with a cloth?
A - No. He handed them uncovered into our hands, and we turned the leaves sufficient to satisfy us.
