The NTSB's narrative for the Cirrus Design CORP SR22 final · quoted from the NTSB record

A loss of separation occurred between a Boeing B737-700 and a Cirrus SR-22. The minimum required instrument flight rules separation between these two aircraft was 1000 feet vertical or 3 nautical miles lateral. The Cirrus had been out of radio contact with air traffic controllers for approximately 90 minutes. Air traffic controllers at the approach control facility requested that the flight crew of the B737 fly as close as safety permits to the Cirrus to look for any visual indications of problems or difficulties. The flight crew of the B737 agreed to the request. The closest point of approach between the two aircraft, both assigned operating altitudes of 11,000 feet mean sea level, was 100 feet vertical and 0.1 mile lateral.
