(CNN) -- The explosive found hidden in a package on a plane in the United Arab Emirates on Friday may have traveled on passenger planes to get there, airline officials said Sunday.

The explosive, along with a similar device found in the United Kingdom, appear to have been designed to detonate on their own, without someone having to set them off, the top White House counterterrorism official told CNN.

"It is my understanding that these devices did not need somebody to detonate them," said John Brennan, President Barack Obama's assistant for homeland security and counterterrorism.

U.S. investigators believe al Qaeda bomb maker Ibrahim Hassan al-Asiri, 28, is linked to that package and another one found on a second airplane in Britain's East Midlands Airport on Friday, a federal official, who was briefed by authorities, told CNN Sunday. Both packages were addressed to synagogues in Chicago, Illinois.

Al-Asiri, who is thought to be in Yemen, is a Saudi who was high on Saudi Arabia's list of most wanted published in February 2009. He is also believed to be the bomber who designed last year's failed Christmas Day underwear bomb.

Separately, an engineering student arrested in Yemen was released Sunday, along with her mother, according to her father, Mohammed Al-Samawi. She was earlier identified as Hanan Al-Samawi, a fifth-year student at Sanaa University in the Yemeni capital, said Abdul-Rahman Barman, a human rights attorney and activist who said he was asked to represent her.

(CNN) -- In the end, it was Scotty who got beamed up.

The ashes of late actor James Doohan, who played chief engineer Montgomery Scott in the original "Star Trek" television series and a series of subsequent films, were on the SpaceX rocket that launched a private spacecraft into orbit this week.

Doohan's character was referenced in the "Beam me up, Scotty" catchphrase associated with "Star Trek."

In various versions of the command, Capt. James T. Kirk, played by William Shatner, would ask his Scottish-descended colleague to activate a matter teleportation device that would transport Kirk or others to the starship Enterprise.

While it is unclear if the exact phrase "Beam me up, Scotty" ever was uttered in a "Star Trek" episode, it became a popular bumper sticker and Doohan chose it for the title of his autobiography published in 1996. He died in 2005.

Celestis, a company that provides memorial spaceflights, confirmed that some of Doohan's cremated remains were among 320 sets on the SpaceX Falcon 9 rocket launched Tuesday.

Stellar week for SpaceX founder Elon Musk

In addition, a portion of the cremated remains of Mercury 7 astronaut Gordon Cooper also were on board, the company confirmed.

The Falcon 9 rocket, which carried up the SpaceX Dragon craft for a possible rendezvous this week with the International Space Station, is expected to remain in orbit for months until burning up when it falls back into the Earth's atmosphere.

"He would rather have flown when he was alive, of course," said Doohan's widow, Wende Doohan, who watched the SpaceX launch Tuesday with the couple's 12-year-old daugher, one of three children from a 31-year marriage. What are the answers to this following set of questions: 1. What was launched recently?
