Parts of a Learjet may have broken off midair before Florida crash that killed 9, investigators say

WEST PALM BEACH, Fla. (AP) — Parts of a business jet likely started to break off even before it slammed into the ground and erupted in a ball of flames in South Florida, killing all nine people on board, a federal investigator said Monday.Video recorded by passersby captured the Bahamas-bound Learjet's rapid nosedive Sunday afternoon before it exploded in Greenacres, about 7 miles (11 kilometers) southwest of West Palm Beach. Flames flickered around chunks of pavement lining the crater as shocked residents looked on in horror. Thick black smoke engulfed the crash site and little remained of the plane.“Debris was everywhere. Debris hit my house. Everything was on fire. The road was on fire,” Anthony Blackmon, who lives near the crash site, told NBC affiliate WTVJ. “I’ve always seen it on the news, never thought it would happen so close to somebody like how it happened today.”Federal investigators outline the probe but decline to speculateNational Transportation Safety Board member Tom C
