The passing of James Doohan, who played Commander Montgomery Scott in "Star Trek," continues to draw reactions and tributes from fans around the world, according to trektoday.com.

Startrek.com featured several tributes, many found on their Letters to the Editor page. Among the reactions from Star Trek notables are:

Rick Berman, who worked with Doohan on "Relics" during "Star Trek: The Next Generation" and the "Star Trek Generations" film, said, "He was a gentle and lovely man, as well as an extremely talented actor. We are all very saddened by this news."

Michael and Denise Okuda, well-known Trek special-effects technicians, said, "Jimmy Doohan was a class act. Jimmy accepted his role as a cultural icon with grace and humor. He was thrilled that he had helped to inspire engineers, scientists, pilots, and even astronauts. To them and to everyone else, he was a symbol of the triumph of human technical ingenuity and grim determination in the face of overwhelming odds."

Eugene Roddenberry Jr., son of Star Trek creator Gene Roddenberry, said, "My father and Jimmy, as I often heard him called, were the closest of the 'Star Trek' cast. I had met Jimmy only a few times throughout the years, and it was always my impression that he was a genuinely good person."

Ronald D. Moore, former Star Trek writer/producer and executive producer on "Battlestar Galactica," said, "You never heard a bad word about Jimmy Doohan the whole time I was at Star Trek. He didn't have any ego clashes with anybody, didn't have an axe to grind Ñ and I think, in a large way, that's also the heart of his character as well. Montgomery Scott was a character without guile Ñ what you saw was what you got with Scotty."

Also on the site are tributes from other well-known figures such as Bjo Trimble, who spearheaded the letter-writing campaign to save "Star Trek;" authors Judith & Garfield Reeves-Stevens; Tim Russ, who played Tuvok on "Star Trek: Voyager;" Official Star Trek Fan Club founder Dan Madsen; and NASA astronaut Mario Runco.

Brent Spiner, who played Data in "Star Trek: The Next Generation," and executive producer Brannon Braga took time during their tour promoting their upcoming CBS show, "Threshold," to honor Doohan. "He was a lovely guy and of course I'm very sad to hear of his passing," Spiner said. "He actually worked a lot with LeVar [Burton], because they both played engineers." Braga said Doohan was a "very charming man and a wonderful actor."

Creation Entertainment's website remembered Doohan's convention appearances and how he related to fans.

"As you perennially regaled your loving audiences, certain themes and stories became treasured riffs that we hoped you would repeat. Everyone knows now what a great character actor you were and how many voices you could create," Adam Malin, president of Creation Entertainment, said.

"Still, it was always fresh when you posed Kirk's immortal plea, 'Scotty, I need Warp power in 20 seconds or we're all dead!' and answered in a variety of characters," he said. "My favorite was Reggie, the British Colonial soldier, whose perpetual response was, 'Well, I'm terribly sorry, Captain, but I can't seem to get the bugger to move!'"

Doohan's ashes are expected to be launched into space on the same flight that will carry the ashes of John Meredyth Lucas, the "Star Trek" writer and director who died in 2002, according to startrek.com. The flight is scheduled to take place in September and performed by Space Services, Inc., who also sent the ashes of Gene Roddenberry into orbit.
