UNITED STATES: A New York couple really will be on cloud nine when they marry later this month: they'll exchange vows in zero gravity.

Noah Fulmor and Erin Finnegan will be floating - possibly upside down - as they say "I do" in a specially modified Boeing 727-200 departing Kennedy Space Center at Cape Canaveral on June 20, a statement from Zero Gravity Corporation said.

They will be "the first bride and groom to be married in zero gravity," the company, a provider of commercial weightless flights, said.

"Richard Garriott, the sixth private explorer in history to go to space and the first second-generation US astronaut, will officiate," the company said.

According to the statement, the aircraft's interior replicates levels of weightlessness found on Mars or the Moon. "It's an experience unlike any other."

Although the betrothed may have trouble with rings floating away, they'll at least get out of the extreme setting unscathed.

The plane is "a zero-gravity playroom, complete with padded floors and walls," said the statement. (AFP)
