In spite of those demonstrated deficiencies, however, Crossair continued to allow Lutz to fly passengers (reportedly due to a shortage of qualified Crossair pilots), and Lutz continued to demonstrate his overall deficiencies as a line pilot. These included a near-miss incident on final approach to Lugano Airport where Lutz came within of colliding with the shore of a lake during his final descent and a navigational error during a sightseeing tour over the Alps that took the flight far off its course to Sion, Switzerland. In this particular incident, Lutz missed his approach into Sion and circled over what he thought was Sion's airport for several minutes before passengers spotted road signs in Italian; the navigation error had taken them over the St. Bernard Pass through the Alps, and the airport they had been circling was in fact located near Aosta, Italy.
