Question: How much time passed between Feith appearing in "Mayday" and "Seconds from Disaster"? Passage 1:Juan Martin del Potro reached the quarter-finals of the first slam of the year in the Australian Open losing to Roger Federer. He then reached his first final of the year at the ABN AMRO World Tennis Tournament losing to Federer once again. However, he bounced back by winning his first title of the year at the Open 13 defeating Michael Llodra in the final. At the Estoril Open, successfully defended his title by defeating Richard Gasquet . At the French Open he reached the quarter-finals but fell to Federer for the fifth time in the year despite leading two sets to love he lost. At Wimbledon he was handily defeated by David Ferrer in the fourth round. He bounced back at the Olympics winning the Bronze Medal match over Novak Djokovic after losing to Federer in the semifinals. At the US Open he reached his third slam quarter-finals of the year but lost once again this time to Djokovic. He won his third title of the year at the Erste Bank Open defeating qualifier Grega Zemlja in the final. At the Swiss Indoors Basel, Del Potro got his fourth championship of the year after beating Roger Federer. This is the third time del Potro has qualified for the event.
Passage 2:During World War II it was one of the few cartridges used by both the Axis and Allied powers, a distinction it shared with the 919mm Parabellum pistol round. Apart from being the standard rifle cartridge of the German and Polish armed forces, it was also used by the armed forces of Great Britain in the Besa machine gun, which was mounted in some of their tanks and other armoured vehicles, as well as being extensively used by the Chinese, especially early in the war. After World War II it was used by the early Bundeswehr of West Germany. Later, when Egypt decided to manufacture the Hakim rifle, a licensed copy of the Swedish Ag m/42, they redesigned the breech to accept the 7.9257mm Mauser cartridge rather than use the original 6.555mm Ag m/42 cartridge. Its military use continues today (2012) in the former Yugoslavia in the Zastava M76 sniper rifle and the license-built copy of the MG 42, the M53 Sarac machine gun.
Passage 3:Feith has appeared on several television series, such as the Canadian Documentary series Mayday (also known as Air Emergency in the United States and Air Crash Investigation in other parts of the world), Survival in the Sky, and, most recently, Seconds from Disaster. He hosted his own short-lived series Secrets of the Black Box on the History Channel, highlighting the major investigations that he led, along with the controversial and conspiracy theory-riddled KAL007 investigation.

He is well known for his frequent public speaking engagements at schools, aviation groups and trade associations.
