Bob Woodruff’s brother David Woodruff discussed Bob’s condition on “Good Morning America” today.

David has been by Bob’s side since the ABC anchor was brought to the military hospital in Germany. Bob is now on his way home to the United States.

“We got a lot of great news this morning,” David Woodruff said. ” He’s improved markedly over the night. He looks much better than he looked the day before. (The doctors said this morning) his signs are great, probably as good as can be expected at this stage.”

Woodruff is still heavily sedated and at this point it is too early to tell what his prognosis might be. He suffered broken ribs, a broken shoulder and skull fracture. He also had some facial wounds on one side of his face.

“The doctors said at the beginning of this, this is not going to be a sprint. This is going to be a marathon,” David Woodruff said. “And we’re committed to making sure we’re there running that marathon with him.”

David Woodruff also cleared up some confusion about what happened after his brother had been hit.

“Bob had come down through the hatch. (Producer) Vinny (Malhotra) picked him up by his lapels. (Bob) opened up his eyes and said, ‘Am I alive?’ And at that point he started to feel the pain. He used some colorful language and said ‘This hurts a lot’ and then he became unconscious.”

The family has been reading the postings on the ABC Web site.

(Bob’s wife) Lee wanted me to tell everyone how much she appreciates the support from everybody, from the team at ABC, from all her friends, family and all the people out there who are praying for Bob and (camaraman) Doug (Vogt),” David said. “I know Doug’s wife would say the same thing.”
