David Blaineis moving his next stunt cross-country…

The 47-year-old part-Puerto Rican illusionist, endurance artist and extreme performer has nixed his plan to float over the Hudson River from New Jersey to New York City strapped to a bunch of helium balloons, blaming logistical challenges.

Instead, Blaine will attempt to perform the stunt — which is being bankrolled by YouTube as an original livestreaming special called Ascension— more than 2,000 miles away in Arizona.

“Because of the complexity of this project, I’m not going forward with my plans to do New York City at this time,” Blaine said in a video announcing the change.

The “groundbreaking R&D flight,” in which he’ll try to fly as high in the air as possible suspended only by balloons, will happen this week in Arizona, he said, “which is the most beautiful backdrop that I’ve ever seen in my life.”

Contingent on the weather in Arizona, Blaine said, his stunt will lift off either Tuesday, Sept. 1 or Wednesday, September 2 at 6:00 am PT.

“Everything is wind-dependent,” he said, encouraging fans to set a reminder on the YouTube livestream page.
