Why are you afraid to answer the question?
What will it take to make you believe that the remains and personal effects came from flight 93?
I'm not, I did.
The personal effects belonged to the people who were on the plane destroyed on 9/11. To the best of my none of the planes on 9/11 have been positively identified.
If you have positive identification (i.e. something with a serial number) that confirms this flight was indeed UA93 I would love to see it.
Now let's talk about Ed Felt, John Shaw, Glenn Cramer, West Moreland County. Afraid to Gravy?
