Federal investigators arrived Saturday on the scene of an airplane crash that killed former Texas Sen. John Tower and 22 other people, one of them an astronaut, Friday near Glynco Jetport.

The probers from the National Transportation Safety Board began their inquiry into the crash of a twin-engine commuter plane as officials used a nearby elementary school as a morgue for the victims, which also included one of Tower's daughters.Glynn County officials did not released the names of those killed in the Atlantic Southeast Airlines crash Friday, but NASA officials at the Johnson Space Center in Houston said the victims also included astronaut Sonny Carter.

Tower, 65, a Republican senator for 24 years whose nomination as defense secretary was defeated in 1989 amid controversy over his personal life, was traveling with his daughter, Marian, 35, en route to Sea Island, Ga., for a party for his new book, "Consequences: A Personal and Political Memoir."

His death came only one day after his former colleague, Sen. John Heinz, R-Pa., was killed in a collision between his plane and a helicopter over a Philadelphia suburb.

Marianne Cassano, a Federal Aviation Administration spokeswoman in Atlanta, said 20 passengers and a crew of three were on ASA Flight 2311, a twin-engine turboprop headed from Atlanta to Brunswick. Atlantic Southeast is a commuter carrier affiliated with Delta Air Lines.

The plane crashed and burned about 2:50 p.m. in a wooded airport about 2 to 3 miles short of a runway at the jetport. Glynn County Police Chief Carl Alexander said there were no survivors.
