After 12 years at the head of the classroom, the tables had turned, and for the first time since graduating from Wilberforce University, Dorothy Vaughan gave herself fully to the discipline that had most engaged her youthful mind. She had come full circle and then some, as she tried to attune her ear to the argot that flew back and forth between the inhabitants of the laboratory, all seeking to answer the fundamental question “What makes things fly?” Dorothy herself had never flown on a plane — something she shared with more than 98 percent of all Americans — and in all likelihood, before landing at Langley, she had never given the question more than a passing consideration. Is their any irony in this paragraph??
