If the mood on the plane that crashed into the side of the Pentagon, American Airlines Flight 77, could have been a color, it would have been a soft, translucent tan, according to a comic book about the Sept. 11, 2001, terrorist attacks.

Yes, that’s right, a comic about the attacks is set for publication next month.

Industry veterans Sid Jacobson and Ernie Colon have collaborated to produce “The 9/11 Report: A Graphic Adaptation,” which is being published by Hill and Wang, the nonfiction imprint of Farrar, Straus and Giroux.

The book condenses the nearly 600-page federal report released by the National Commission on Terrorist Attacks Upon the United States to fewer than 150 pages, and the creators say they hope their book will help attract young readers and others who might be overwhelmed by the original document. With sans-serif captions, artist renderings, charts and sound-describing words such as “Whooom!” and “R-rrumble,” the adaptation recounts the attacks with parallel timelines of the four hijacked planes.

But can a topic as massive and sobering as Sept. 11 be dealt with effectively in the pages of a comic book?

When a first draft of the book came across his desk, Hill and Wang publisher Thomas LeBien said, he was “absolutely struck with it potentially being a wonderful idea.”

Jacobson and Colon worked hard to “make sure we were both honest and respectful,” LeBien said.

Jacobson, emphasizing that he used “99 percent” of the commission’s words in the adaptation, said: “We very possibly fell into some comic book tricks, but it truly didn’t bother us, and for the most part, it shouldn’t bother people.”

Jacobson, 76, creator of “Richie Rich” series, once was editor in chief of Harvey Comics. Colon, 75, who drew “Richie Rich” and “Casper” for 25 years, worked for Harvey before a short stint as an editor at DC Comics, the home of characters such as Green Lantern, Wonder Woman, Superman and the Flash. He also illustrated for Marvel Comics, where Spider-Man and the X-Men were created.

Jacobson and Colon began the 9-11 project about 1 1/2 years ago, after Colon learned that the commission’s report was in the public domain and that several movie producers were considering basing films on it.

“There are going to be a whole bunch of kids, teenagers and adults that will not read the report,” Colon said, adding that comics might offer an alternative. “The educational system at large has resisted them, I think, because of the term ‘comic book.’ I like to think of them as something that has more purpose.”

Concerned commission

The effort for the two longtime collaborators and friends was bicoastal. Jacobson, in Los Angeles, e-mailed what he visualized to Colon, on Long Island, who would scan in his drawings and send them back.

LeBien sent the book to the commission’s former top officials in hopes of winning their approval. He got more than that.

“When I first heard about it, I was very concerned,” said former New Jersey Gov. Thomas Kean, who chaired the commission. “But when I looked at it, it was absolutely accurate.”

He and Vice Chairman Lee Hamilton wrote a foreword for the comic, which includes an adaptation of the report card on how the commissioners’ recommendations have been implemented. Kean said he hopes the comic book will lead more audiences to the original report, which landed on best-seller lists after its release two years ago.

“I didn’t think we’d be a best seller, and I didn’t think we’d be turned into a comic book,” Kean said.

This isn’t the first time difficult topics have been tackled graphically. In “Maus,” which won a Pulitzer Prize in 1992, comic book artist Art Spiegelman tells the story of his father, a Holocaust survivor. Marjane Satrapi remembers life as a girl during the Islamic revolution in “Persepolis,” a graphic autobiography. Spiegelman’s comic book diary about his Sept. 11 experiences, “In the Shadow of No Towers,” was published in 2004.

But as the nation approaches the fifth anniversary of the Sept. 11 attacks, just how ready are Americans to see those events recounted in the popular culture, be it a comic book or feature film?

“United 93,” the feature-length film about the fight between hijackers and passengers on the plane that crashed in Pennsylvania, didn’t attract audiences when it was released in April. Another test will come next month, when Oliver Stone’s “World Trade Center” will be released.

LeBien resists comparisons to Hollywood films. “This adaptation is very different,” he said, emphasizing that the book uses only the facts of the commission’s report. “The thing that I worry about most is that people will make that kind of conflation.”

Earning respect

No matter how well-done or factual a work is, there is still emotional fallout for the families of 9-11 victims, said Caitlin Zampella, interim executive director of a nonprofit survivors group, Families of September 11 Inc. The organization listed on its Web site the theaters where trailers for “United 93” were appearing, for example, so that families would not be taken by surprise.

“We can’t control what people do or don’t do, but we encourage people to practice good self-care,” she said.

LeBien said, “If somebody picks it up and looks at it and starts to read it with some care, they’ll understand that it’s respectful.”
