Never saw a B-58, would have loved to, one of the favorite models I built. Recently read a book by a B-58 pilot of his days flying them.
Coolest boom and sighting I ever had was a B-70 in early 1967 up in the high desert of Nevada. He was really hauling the mail way up there, no mistaking that white shape. Righteous boom well after he passed overhead. No idea how high he was.
My B-58 experience was very low. It removed the snow from the pine trees. From that moment the Hustler became my favorite USAF plane.
