It has been weeks coming but finally US F1 have stopped operations and admitted they are not going to make it onto the grid in 2010. Although there is no direct quote from the team, there have been several tweets from the inside, and Autosport has the story:

AUTOSPORT understands that shortly before lunchtime, production manager Dave Skog informed those staff who had remained at the team during its recent troubles that they were being laid off.

Updated: Futher to the original story, Autosport have posted more information, this time from team boss, Ken Anderson.

Ken has pointed out that the team still have hopes for a 2011 entry to the grid and confirmed that operations have been put on hold at the factory.

We are waiting for a reply from the FIA and are working with them. In the mean time, there is nothing for the employees to do, so we have told them to stop working on the current car until we have a decision.
