Every good pilot could do an ordinary “loop the loop” with the pilot on the inside of the loop. But most people thought a loop with the pilot on the outside was impossible, because neither the pilot nor the airplane could withstand the forces involved. But Jimmy Doolittle believed otherwise, and he became the first to perform an outside loop in May 1927.
