Narrative:
Rapid depressurization, initiated emergency descent from FL330, then notified ATC. ATC gave us clearance to 15000 ft. At 15000 ft we requested 12000 ft and direct to hou. That clearance was given once level at 12000 ft we canceled emergency status. Flew to hou, normal landing. There were no conflicts with other traffic. We left FL330 before we received a clearance. Clearance was given on request. On feb/thu/98, I called ZMP and asked about any conflicts. They said there would be no action taken on the event.
