Four people were killed in a New Year's Eve plane crash in Colorado as snowstorms swept the Rockies and Midwest.

Later, a television news helicopter from Denver made a forced landing in a heavy storm while flying over the Rockies to cover the fatal crash. Authorities said four people were stranded on a snowbound mountainside near the Continental Divide.

The helicopter pilot radioed that the four aboard were not injured. Sheriff's deputies spent about six hours searching for the helicopter on snowshoes and in snowmobiles but gave up when the weather became too severe. The hunt is to resume at daybreak this morning. All four were reported to be wearing warm clothing, and the pilot radioed that he would be conserving battery power.

Earlier, a twin-engine commuter plane operated by Sun West Airlines crashed in snow and fog near Durango, Colo. Besides the four killed, two children were critically injured. A Federal Aviation Administration official said the pilot missed an approach during an instrument landing attempt. He applied full power and climbed, intending to approach the runway again when the plane crashed. The plane had left from Albuquerque, N.M.

In Philadelphia, rain forced postponement of the Mummers Parade; in Atlanta, cold weather forced cancellation of the Peach Bowl Parade.
