The widow of space shuttle Challenger pilot Michael Smith, who sued the makers of shuttle rockets blamed for the Challenger explosion, says she will be praying for the safety of the next shuttle crew.

Shuttle Discovery - which has undergone 210 modifications and seven months of delay - will be the first shuttle flight since Challenger exploded in January 1986 killing all seven aboard. The launch is scheduled for Sept. 4.

"I'll be saying my prayers for the crew and their families," Jane Smith told The Houston Post after giving a tearful deposition on Wednesday to lawyers for U.S. government contractor Morton Thiokol. "I hope they'll be safe."

Mrs. Smith and her three children are the only relatives of the Challegner crew who haven't settled a lawsuit with the government or Thiokol.
