MOJAVE, Calif., July 28 — British entrepreneur and adventurer Richard Branson on Monday took the wraps off an aircraft that, for $200,000 a seat, may someday take tourists who can afford it on the first leg of regular, albeit very brief, commercial flights into space.

Amid extravagantly orchestrated publicity at a historic test airfield near Edwards Air Force Base, Branson unveiled the double-hulled “mother ship” built to carry a capsule filled with six wealthy tourists high into the stratosphere, from where the smaller ship would rocket into the blackness more than 60 miles above Earth.
The dual-fuselage, all-composite plane expands and refines the smaller version that famed aircraft designer Burt Rutan twice used four years ago to begin the journey of a piloted capsule to sub-orbital altitude, winning the X-Prize competition aimed at encouraging private spaceflight.
No one knows when Virgin Galactic will fly, but about 100 people have already paid full price for the trip, which comes to $50,000 per minute for the four minutes the travelers will spend in weightlessness. An additional 170 have put down deposits.

Mac OS X’s reputation for security was tarnished Thursday when a team of researchers from Independent Security Evaluators (ISE) managed to hack a MacBook Air in two minutes using a zero-day vulnerability in Apple’s Safari 3.1 Web browser.

The ISE security researchers — Charlie Miller, Jake Honoroff, and Mark Daniel — were participating in the “PWN to OWN” competition at the CanSecWest security conference, which began Wednesday in Vancouver, British Columbia.

“Pwn” is computer gaming slang for “own,” as in conquer. The “p” typo serves to heighten the humiliation of defeat by emphasizing that the loss came at the hands of a youth who can’t even spell or type correctly. The term has also come to be used in security circles.

Contest participants had their choice of trying to hack an Apple MacBook Air running OS X 10.5.2, a Sony Vaio VGN-TZ37CN running Ubuntu 7.10, or a Fujitsu U810 running Vista Ultimate SP1. During the first day, when attacks were limited to network attacks on the operating system, no one managed to compromise any of the systems.

That changed Thursday when attacks on default client-side applications — Web browser, e-mail, IM — were allowed. The ISE team won $10,000 from security firm TippingPoint Technologies for compromising the MacBook Air.

The undisclosed vulnerability in Safari 3.1 has been shown to Apple and no further information about it will be revealed until Apple can issue an update, TippingPoint said.

In a blog post on Friday, TippingPoint said, “[S]ince the Vista and Ubuntu laptops are still standing unscathed, we are now opening up the scope of the targets beyond just default installed applications on those laptops; any popular third-party application (as deemed ‘popular’ by the judges) can now be installed on the laptops for a prize of $5,000 upon a successful compromise.”

Apple did not respond to a request for comment.
