The letters to Helen Day are out there available and were from the world flight.
What are these letters your refer to suspected to be...and how are they suspected to be different?
Thanks!
If these are letters I think they are, they are letters Fred wrote to his wife Mary Bea during the world flight and may also include correspondence with Hollywood actor Eugene Pallette. Mary Bea's birth name was Passadori and, before she died (or as part of her estate), the Passadori family ended up with the letters. In 1998, former TIGHAR member Don Jordan convinced the Passadori family to let him photograph one of the letters Fred Wrote to Mary Bea (attached)and
a letter Fred wrote to Gene Pallette but they would not release several other letters.
