O livro é provavelmente Rocket Man de Lee Correy ( AKA, G. Harry Stine).
"My name is Tenzing Sonam of Sola Khumbu, Nepal. This is my friend, Posang Tharkey." He extended his hand. When I saw the alpine ice axe leaning against the foot of the bed, the problem was solved! I remembered the old photographs of the conquest of Mount Everest. These two boys were Sherpas!
With a grin, I asked, "Sola Khumbu is close to Everest, isn't it?" "It lies in the shadow of the Goddess Mother of the World, yes," Posang Tharkey answered. "What are you doing in New Mexico ?"
"We're Co-ops," Tenzing Sonam answered proudly. "Rocket engineers ?"
One of the first things they did was unpack some Tibetan tea. It wasn't the usual kind of tea I knew. It came in little bricks instead of powdered form. Then Posang got some butter, salted it, and treated Ham and me to an ancient Sherpa social drink; Tibetan tea with salted butter. I didn't like it at first, but later the taste grew on me.
"This is not truly Tibetan tea," Tenzing pointed out.
"In Sola Khumbu, we use rancid yak butter. But you don't have yaks here . . . only ridiculously fat cows!"
Frankly, I was quite happy that there were no yaks in New Mexico. Ordinary salted butter was good enough for me!
