Narrative:
A Boeing 757-222 operated by United Airlines sustained substantial damage in a landing accident at Denver-Stapleton International Airport, CO (DEN/KDEN).
The first officer, who was flying the airplane, was making a visual approach to runway 26R. Although the approach was stable from 500 feet, the landing flare was initiated late, and the airplane touched down firmly. It bounced slightly and assumed a nose high attitude. When it touched down again, the tail scraped the runway.

Probable cause:
The first officer's improper recovery from a bounced landing. Factors were: the first officer's delayed initiation of the flare, and the captain's improper supervision of the flight.
