I seen this on another reddit post(linked in comments) I am not sure how authentic the statement is.
But about a 3rd of the way through it mentions the below paragraph.
“One saucer was so enormous and the logistic problems in transportation so enormous that it was buried at the crash sight and remains there today”
I found this quite interesting, especially as Ross Coulthart reported a similar story last month to do with a huge UFO buried.
