Service for Apollo astronauts begins somber week for NASA

CAPE CANAVERAL, Fla. - It was supposed to be a routine launch-pad test.

But from the Apollo 1 command module at Pad 34 came a panicked voice saying, "Fire in the cockpit."

Exactly 40 years later, the three Apollo astronauts who were killed in that flash fire were remembered yesterday for paving the way for later astronauts to travel to the moon. The deaths of Virgil "Gus" Grissom, Ed White and Roger Chaffee forced NASA to pause in its space race with the Soviet Union and make design and safety changes that were critical to its later successes.

"I can assure you if we had not had that fire and rebuilt the command module . . . we could not have done the Apollo program successfully," said retired astronaut John Young, who flew in Gemini 3 with Grissom in 1965. "So we owe a lot to Gus, and Rog and Ed. They made it possible for the rest of us to do the almost impossible."

The memorial service at the Kennedy Space Center Visitors Complex marked the start of a solemn week for NASA - today is the 21st anniversary of the space shuttle Challenger accident, and Thursday makes four years since the space shuttle Columbia disaster.

Chaffee's widow, Martha, and White's son, Edward 3d, along with NASA associate administrator Bill Gerstenmaier, laid a wreath at the base of the Space Mirror Memorial, a tall granite-finished wall engraved with the names of the Apollo 1, Challenger and Columbia astronauts and seven other astronauts killed in accidents.

Chaffee, 69, remembered feeding her two children hot dogs for dinner that night in 1967 and knowing something was wrong when astronaut Michael Collins showed up at her home to tell her about the accident.

"My first reaction was, 'What could have happened? He's not flying,' " she recalled before the ceremony.

NASA also hadn't considered the countdown drill hazardous, anticipating accidents only in space. Fire rescue and medical teams were not at the launch pad. No procedures had been developed for the type of emergency the Apollo 1 crew faced. The work levels around the spacecraft contained steps, sliding doors and sharp turns that hindered emergency responses.

An investigation concluded that the fire most likely started in an area near the floor around some wires between the oxygen panel and the environmental control system. The 100-percent-oxygen environment made it highly combustible, and internal pressure made it impossible for the astronauts to open the command module's inner hatch.

The astronauts died from inhaling toxic gases.
