Notebook: Agency knew about plane flaw but didn't tell
Dubuque was actually 36 miles. Clinton was 12 miles. Moline was 36 miles.
The dialogue suggests that one or both pilots saw the Clinton strip. One of the crew replied to the Chicago controller.
“Ah, that’s Dubuque off ah to our left and 25?”
The controller responded, “Affirmative, that’s Dubuque airport.”
Dubuque was to the right and north. Clinton was to the left and south.
That piece of the conversation took place about 3:41 p.m. Just four minutes earlier, the state plane had been cruising west at an altitude of about 24,000 feet.
At 3:44 p.m. the crew turned the plane north toward Dubuque. They now were down to 6,000 feet.
At 3:47 the crew asked the controller to have an ambulance standing by at Dubuque. A minute later the controller was told for the first time that the two-engine plane was down to one engine.
At 3:50, with the plane down to 1,900 feet, the Dubuque controller took over and told the crew they were about 10 miles southeast of the Dubuque airport.
A minute later came the last contact between the Dubuque controller and the crew. The Dubuque controller gave them the frequency for the Dubuque tower. “Thanks,” one of the crew responded.
