Arheologi Oregonas piekrastē pēta kuģa atliekas, kas nogrima pirms vairāk nekā trīssimt gadiem. Amerikas pamatiedzīvotāju mutvārdu stāsti vēsta par kuģa bojāeju un izdzīvojušajiem. Kuģa porcelāns un bišu vasks joprojām tiek izskaloti krastā. Arheologi rekonstruē nogrimušo vraku, izmantojot vēsturiskos datus un savas zināšanas, atklājot, kā šis milzīgais kuģis pārvadāja simtiem tonnu kravas gandrīz pāri puspasaulei.

A small commuter plane begins a short flight when disaster strikes. Moments after takeoff, the nose of the aircraft pitches up dramatically. The flight crew struggles for control.

No Boeing 737 lidmašīnas pāri paliek tikai apdedzis vraks. Tiek apstiprināta visu 88 cilvēku, kas atradās uz klāja, nāve. Sākotnēji izmeklētājiem ir aizdomas par zināmu konstrukcijas kļūdu lidmašīnas stūres iekārtā.

Visi 162 lidmašīnā esošie cilvēki ir miruši, un starptautiska izmeklētāju komanda pievienojas vietējiem ekspertiem Džakartā, lai noskaidrotu, kas noticis. Neviena no melnajām kastēm neatklāj visu stāstu, taču ir skaidrs, ka kapteiņa noslēpumaina rīcība, lai novērstu rutīnas kļūmi, izraisīja nāvējošu notikumu virkni.

Ceļā uz Dienvidkorejas Kimhes starptautisko lidostu Boeing 767 ietriecas kalnā vairākas jūdzes no skrejceļa.

Deviņdesmitajos visur saradās kameras, kas veicināja mūsu apsēstību ar sevi. Kameras dodas līdzi kruķiem, bet ķermeņa videokameras viņus tur grožos. Ziņu helikopteri dzenas pakaļ O. Dž., kamēr tiesas kameras filmē viņa prāvu. Ar videokameru uzfilmēta šausmene liek mums apšaubīt realitāti, bet "The Real World" maina pasauli kā revolucionārs raidījums, kas mūs ieved realitātes šovu gadsimtā.

The tranquillity of Montserrat, an island paradise in the Caribbean, is shattered in 1995 when the Soufriere Hills erupt for the first time in recorded history. The eruption takes the population of Montserrat by surprise. Scientists flock to the island and closely monitor the volcano over the next two years. Evacuations take place and an exclusion zone is mapped out. Then at 12:45pm on June 25th 1997 two years after the first eruption a massive tremor rocks the mountain. A plume of hot ash and steam soon spews into the air; reaching 45,000 feet in a matter of minutes and shrouding half the island in darkness. There follows 25 minutes of violent activity. When the ash finally settles many hours later, a scene of total devastation is revealed; many villages are buried and 19 people are dead. Many others are lucky to be alive.

Do amazing breakthroughs in technology bring terrifying new levels of danger to humanity? We this deadly question by exploring some of the dangers posed by one of the most promising new technologies: nano-robotics. This one-houir program postulates an environmental clean-up robot the size of a molecule, which is hacked by a rogue engineer and turned into a spreading, flesh-consuming monster. In this scenario, it becomes clear that the only technology fit to fight back against this nano-robot is another robot a near-microscopic nano-aircraft built by the American military. The nano-weapon does handle the initial threat but when it spins out of control and begins attacking cities around the world, the cure becomes more deadly and world-threatening than the disease. Only by resorting to an improvised weapon radar used to fuse and melt the tiny inner workings of these military robots does humanity escape this gruesome fate.
