Question: How many years after Chicago Air went defunct was Chicago Express Airlines established? Passage 1:The airline was established in 1993 by Mike Brady of Express Airlines I in Atlanta, Georgia. The airline started operations in August 1993. Its route structure in many ways mimiced an unrelated defunct predecessor named Chicago Air which also operated from Chicago Midway's airport less than a decade before. On June 1, 1999, Chicago Express became a wholly owned subsidiary of Amtran, later known as ATA Holdings and now Global Aero Logistics, and operated as ATA Connection, a regional code sharing affiliate of the now defunct ATA Airlines (formerly known as American Trans Air). Chicago Express' principal base of operations was Chicago Midway International Airport, where the company maintained its headquarters. For several months before its liquidation, the company also operated a hub in Indianapolis, part of ATA's failed plan for intrastate flights throughout Indiana. However, following ATA Holdings' decision to codeshare flights with Southwest Airlines, a decision was made to terminate Chicago Express effective March 28, 2005, in favor of a strictly mainline operation. CSC Investment Group, Inc., headed by CEO Edward S. Halley, purchased the airline in 2005 for $3.2 million.
 Passage 2:In 1979, he branched out from his radio work to co-host with Jeanne Beker the music newsmagazine The NewMusic on CITY-TV until 1985. The New Music was a pioneering program that pre-dated MTV. Roberts, Beker and the New Music team won many awards for their work. During that time, Roberts also served as Entertainment reporter for CITY-TV and on occasion filled in for John Majhor and later Brad Giffen on CITY-TV's local music video show Toronto Rocks. In 1984, Roberts was tapped to front Canada's music channel MuchMusic. He and Christopher Ward were the first on-air personalities appearing when the network launched in 1984. At MuchMusic he hosted many programs, including a one-hour heavy metal video show called The Power Hour.
