Fall Out Boy rocker Pete Wentz is devastated after the rockers were forced to scrap plans for an around-the-world-in-a-day tour altogether.

The group was scheduled to kick off their ambitious seven-continent record-breaking trek on Tuesday, but was forced to postpone the trip - which included a show in Antarctica - due to bad weather.

They had hoped to embark on the rescheduled trip on Wednesday, and even planned to use a special aircraft that can land in the most adverse weather conditions.

Describing the Hercules plane on his online blog, bassist Wentz writes, "(The plane) has four propellers and is used for take-offs and landings in conditions with bad runways and bad weather."

But their efforts were thwarted when pilots advised them not to go ahead with their trek because it was too dangerous.

Wentz says, "It's an utter f**king disappointment... It's so insane. We had this idea, and then to not be able to fulfil it is just disappointing, especially when you put it out there. But what are you gonna do, wait until winter's over?"

And Fall Out Boy frontman Patrick Stump fears their cancelled trip will upset Guinness World Records chiefs so much, they won't respond the next time the band attempts a similar feat.
