A US Navy Blue Angels jet crashed during a practice run in preparation for a weekend air show in Tennessee.
Onlookers stood stunned across Smyrna, a town to the southeast of Nashville, as the jet careened toward the ground, erupting in a fireball and cloud of black smoke.
Rutherford County fire chief Larry Farley confirmed that one person had been killed in the crash.
This crash is the second for a military demonstration aircraft in a single day -- an exceedingly rare occurrence.
