Clayton Knight, The non-stop stowaway (1928)
“ The air bumps here were terrific, tossing them about, and the Skipper was obliged to keep his eye constantly on the bank and climb indicator in order to keep the plane on anything resembling an even keel. As they had entered the clouds the wind had been nearly dead astern, and here in the murky darkness they were compelled to trust solely to their instruments for navigation. The wind caught them up in fierce eddies, and swirls of gray clouds sucked up past them. Flashes of lightning darted here and there. The plane seemed to have no more stability than a kite. ”
