Narrative:
Delta Air Lines flight 1889 from Boston, MA (BOS) to Salt Lake City, UT (SLC) diverted to Denver, CO (DEN) after sustaining substantial damage to the nose cone and windshield due to hail.
The aircraft was en route at FL340 when it entered an area of intense hail.
The crew initiated a descent at 20:16 hours local time. A safe landing was made at Denver about 20:43 hours.

The National Transportation Safety Board determines the probable cause(s) of this incident as follows:
The flight crew's continued flight into a closing gap between areas of thunderstorm activity and their failure to maintain the required lateral separation from the thunderstorms, which resulted in the airplane's encounter with hail and subsequent airplane damage.

Contributing to the incident were the company flight dispatcher's failure to provide complete and timely weather information to the flight crew and the Denver air route traffic controller's failure to provide significant pilot weather report information and alert the pilots of existing and worsening hazardous weather along their flight route, as required by Federal Aviation directives, both of which led to the airplane's encounter with hail.
