According to the article, there was an unexpected plane that landed in Iran. The plane belonged to The Bank of Utah, and apparently it had an American flag on the tail of the plane. The reason why this was a big deal is because "President Obama has warned that Iran is not open for business, even as the United States has loosened some of its punishing economic sanctions as part of an interim nuclear pact." The plane had no actual reason of being there and people don't know why it was in Iran. Apparently when asked, one of the executives in Salt Lake City, Brett King said that "We have no idea why that plane was at that airport."
"The tracking of planes has become a kind of global sport, as largely amateur photographers post thousands of images showing arrivals and departures in their attempts to chronicle flight paths. In the case of this plane, for example, one spotter spied it leaving an airport in Zurich around the time of the World Economic Forum in Davos, Switzerland, held in January. Another photographer tracked the plane, identified by its call letters N604EP on the tail engines, departing a London-area airport for Ghana last October."
