JEKABPILS, Latvia (AP) — Latvian couples have tied the knot in the air on Valentine's Day hoping to set a world record in the number of simultaneous weddings in hot air balloons.

Fifty couples in 30 balloons rose into the sky Sunday during the Love Cup festival near the southeastern city of Jekabpils, watched by thousands of spectators but the balloons were hitched to cars because it was snowing at the time, impeding them from rising higher than some 15 meters.

It wasn't immediately clear if the ceremony would qualify for an entry in the Guinness Book of World Records as the largest airborne wedding in hot air balloons.

The event was watched by independent observers, including a Guinness representative who couldn't be reached for comment.
