The Twin Cities' Metropolitan Airports Commission took a small step today (Tuesday) toward building a link with the Rochester airport as a way to ease congestion. The commission agreed to spend 25-thousand dollars to see if the idea has any support. Minnesota Public Radio's Art Hughes reports. {Rochester airport officials have been busy in recent years developing their facility. One runway was recently lengthened to 75-hundred feet and another is scheduled to be expanded to nine thousand feet to accomodate larger planes. Rochester has a new cargo facility, the main terminal is being expanded and just this week TWA began flights to St. Louis. Rochester Senator Shiela Kiscaden appeared before the Minneapolis-St.Paul Airports Commission to begin what she calls a 'formal alliance' to see whether Rochester and the Twin Cities can compliment each other's air traffic needs.
