In 1887, a glacial geologist named George Frederick Wright was hiking across the Muir Glacier in southeast Alaska when something strange caught his eye. Just as the daylight began to fade, the previously uninterrupted expanse of white snow around him began to develop what appeared to be a five o’clock shadow. These wriggling “whiskers” grew rapidly and emerged from the solid ice, leaving the snow crawling with an astonishing number of small black worms. Within approximately an hour there were tens of thousands of them criss-crossing the snow as far as he could see, leaving nary a square inch unwormed. A few hours later they began to slip effortlessly back into the ice, ultimately leaving nothing but pure white snow behind for the morning sun. The ice scientist brought news of these strange ice worms back to polite civilization, yet even over a century later little is known about the intriguing organisms.

It was half past midnight on March 17th, 1968. Keith Smart, the director of epidemiology and ecology at Utah’s Dugway Proving Grounds, was awakened by the ringing of a phone. On the other end was Dr. Bode, a professor at the University of Utah, and the director of the school’s contract with Dugway. There was a problem. Calls had been coming in. About 27 miles outside of the base, in the aptly-named Skull Valley, thousands of sheep had suddenly died. There were some survivors among the flocks, but it was clear that their hours were numbered. Veterinarians were dispatched to euthanize the few remaining animals.

Army officials began drafting their official denial. A few days earlier, one of their planes had flown high over the Utah desert at Dugway with a bellyful of nerve agent. The plane’s mission was simple: using a specially rigged delivery system, it was to fly to a specific set of coordinates and spray its payload over a remote section of the Utah desert. This test was a small part of the ongoing chemical and biological weapons research at Dugway, and it was one of three tests held that particular day. The flight would soon prove to be far more important than anyone could have guessed at the time.

An EEG machineWithin a nondescript university laboratory, a neurobiologist reads aloud from her list of prepared phrases. In the adjoining room, a volunteer listens attentively with a collection of colorful wires trailing from his head. The needles on the electroencephalograph (EEG) flutter with each utterance, but most of the phrases prompt little discernible reaction from the testee. Among the long list of experimental sentences, however, a few provoke a peculiar response. The volunteer’s face muscles contract, and his body begins to convulse. His breathing becomes spasmodic, and he makes a series of involuntary, repeated vocalizations. For one informative moment, the EEG’s mechanical scribblings flap rapidly from margin to margin, providing a nugget of neurological gold.

The affliction under study is surprisingly common among humans. Though the episodes are usually transitory, they will occasionally erupt as intense, prolonged outbursts where bodily fluid containment is placed in jeopardy as the hapless victim collapses into a moist, quivering, rhythmically-vocalizing mass. Alarmingly, the phenomenon is highly contagious, and in extreme cases, it can even lead to death. Taken together, these remarkable bizarre symptoms are known as laughter, and although it is universal among human races and cultures, its processes and purpose are not yet fully understood.

Vela SatelliteOn 22 September 1979, sometime around 3:00am local time, a US Atomic Energy Detection System satellite recorded a pattern of intense flashes in a remote portion of the Indian Ocean. Moments later an unusual, fast-moving ionospheric disturbance was detected by the Arecibo Observatory in Puerto Rico, and at about the same time a distant, muffled thud was overheard by the US Navy’s undersea Sound Surveillance System (SOSUS). Evidently something violent and explosive had transpired in the ocean off the southern tip of Africa.

Examination of the data gathered by satellite Vela 6911 strongly suggested that the cause of these disturbances was a nuclear device. The pattern of flashes exactly matched that of prior nuclear detections, and no other phenomenon was known to produce the same millisecond-scale signature. Unfortunately, US intelligence agencies were uncertain who was responsible for the detonation, and the US government was conspicuously reluctant to acknowledge it at all.

The passenger manifest for British South American Airlines (BSAA) flight CS-59 might have made a perfect character list for a murder-mystery. Aboard were two businessman friends touring South America on the lookout for trade opportunities: a fun-loving Swiss and a self-made English executive. Also travelling were a Palestinian man who was rumoured to have a diamond stitched into his jacket, and a South American agent of the Dunlop tyre company who had once been the tutor to Prince Michael of Romania. The oldest passenger was in her seventies, a widow of German extraction returning to her Chilean home after an inconvenient World War had unexpectedly extended her stay abroad. And to add a whiff of espionage, a member of a select corps of British civil servants known as King’s Messengers joined the flight, carrying a diplomatic bag bound for the UK embassy across the border.

The date was August 2nd, 1947, and the flight was scheduled to depart from Buenos Aires, Argentina, bound for Santiago, Chile. The intrepid voyagers were to fly in the Star Dust, a shiny Lancastrian aircraft derived from the legendary Avro Lancaster World War II bomber. Its aircrew were ex-Royal Air Force to a chap, and the machine was captained by an experienced and decorated wartime flyer named Reginald Cook. Traversing the Andes Mountains in atrocious winter weather was an undertaking that would demand all his knowledge and skills, yet the journey should have been well within the capabilities of both man and machine.
