Nova visits Russia for Nova: Top Gun Over Moscow, a thorough look at the sleekest and most powerful Russian jets. In a word, they are tough. These jets are engineered quite differently from their American counterparts. They function well in adverse conditions, able to take off from open dirt fields, and their continuous operation doesn't depend on regular maintenance. The U.S. jet is finely tuned, requiring more frequent upkeep, but definitely having a high-tech edge, particularly in the areas of radar and missile guidance. Interviews with pilots reveal a very different outlook between the two countries on training goals.

NOVA documentary inquiring into the fate of early Everest explorers George Mallory and Sandy Irvine

It was one of humankind's most epic quests - a technical problem so complex that it challenged the best minds of its time, a problem so important that the nation that solved it would rule the economy of the world. The problem was navigation by sea—how to know where you were when you sailed beyond the sight of land - establishing your longitude. While the gentry of the 18th Century looked to the stars for the answer, an English clockmaker, John Harrison, toiled for decades to solve the problem. His elegant solution made him an unlikely hero and remains the basis for the most modern forms of navigation in the world today. This film will be both a celebration of Harrison's invention and an adventure story. An expedition on a period sailing vessel as it sails the open sea will demonstrate the life and death importance of finding your longitude at sea.

US federal investigators are called in to determine the cause of a mysterious jetliner crash in Panama. Nothing about the accident makes sense, until a key clue emerges.

To many of us they are a figure of fancy on par with the unicorn. To scientists, however, the seahorse is a fascinating object of study. Unlike other animals, in seahorses it is the male who get pregnant and gives birth. But to populations around the world, the seahorse is something else again; considered a source of sexual prowess to proponents of traditional Chinese medicine, the magical seahorse is also a crucial source of income to fishermen in the Philippines who harvest and sell them to that burgeoning trade.

The mission was impossible. The Odds were astronomical. The results were spectacular.
