Authorities say a skydive instructor and a student who jumped separately have died in Florida. The skydivers, both men, were part of a jump Saturday in Zephyrhills, about 30 miles northeast of Tampa. Authorities say the plane took off about 10:30 a.m. and 22 people jumped. When only 20 returned, authorities started searching for the missing men. The bodies were located about 7:30 p.m.
