“This gave us confidence to proceed concurrently with full-scale development and low-rate production.” Such components either were transferred directly to the F-117 or were used in modified form. “Using proven components from other aircraft allowed us to reduce risk,” notes Mr. The 37th Tactical Fighter Wing (known then as the 4450th Tactical Group) achieved initial operational capability with the F-117A on October 26, 1983, a mere twenty-eight months after first flight. Bill Park, Lockheed’s chief test pilot, took the F-117 aloft for the first time on June 18, 1981, Mr. Using streamlined management methods and operating under tightest secrecy, cadres from Lockheed and Air Force Systems Command’s Aeronautical Systems Division cooperated closely to get the F-117 built and flying just two and a half years after work began. “It is an odd-looking flying machine,” says Ben Rich, Lockheed’s executive vice president and general manager of the Skunk Works, “but we got it operational in record time.” Lockheed’s Advanced Development Projects (ADP) section–popularly known as the “Skunk Works “–got the task of building a production “stealth” fighter. Soon after, the Air Force decided to proceed into full-scale development. The classified program, called Have Blue, produced and flew several subscale proof-of-concept air vehicles. In the mid-1970s, the Defense Advanced Research Projects Agency provided funding for development of an airplane that would feature low radar, optical, and infrared signatures to counter the increasing sophistication of Soviet radar and surface-to-air missiles. It was the first time anyone outside the program, including the families of the unit’s pilots and maintainers, had seen the mysterious F-117 up close. They circled, touched down, and taxied to a reviewing stand filled with onlookers. On April 21, two F -117 pilots flew their planes from Tonopah Test Range, Nev., to Nellis AFB, Nev. This spring, the curtain of secrecy finally began to part. Only in November 1988, however, did the Pentagon even acknowledge that the F-117A existed, and then it said little more than that the aircraft had been built for maximum stealthiness. Nearly a dozen years ago, in December 1978, the Air Force decided to develop a full-scale, radar-evading fighter. Now the world is getting its first close look at one of history’s most unusual combat aircraft. Masks with clear sections over the mouth, developed to aid deaf people, may be an option.The Air Force and Lockheed got the F-117 A fighter built and flying in a mere thirty-one months, but kept it under wraps for eleven years. Not being able to see an epileptic child’s face can be a safety risk if they have distinctive pre-seizure facial expressions. Epilepsy: A significant percentage of autistic children have seizure disorders.Autistic people can be extra sensitive to smell, so be sure your child brushes their teeth before trying on a mask. Smell: I nearly passed out from my own mask-confined coffee breath.There are fixes, such as tucking a tissue between the mask and the bridge of your nose or changing your breathing pattern, but these solutions may not work for people with sensory issues or developmental disabilities. Visibility: If your child wears glasses, masks may fog them up.One enterprising mom fixed the latter issue by sewing buttons on her son’s favorite hat and pulling the elastics around those instead. Some kids can’t bear the feeling of mask elastics pulling on their ears. Sensory: My son can’t stand having anything covering his face.For some autistic people, this can feel like suffocation. Anxiety: A mask doesn’t block breathing, but it does change the feeling of one’s airflow.
