More than 20 years in service with United, but still going strong! United had their Eights re-engined during the early 1980s, and continued to operate them well into the 1990s. Most were later sold to various operators and converted to freighter. That included N8081U, which became SE-DLM with Time Air Sweden in 1992, and N827BX with Burlington Air Express in 1993. It was sold for scrap in 2004.
