Alert levels at the White House and Capitol were raised to their highest state, red, on Wednesday when a Cessna 152 crossed into restricted air space and failed to respond to a Homeland Security helicopter scrambled to stop it. Military jets fired four warning flares at the singleengine aircraft, which was carrying a pilot and a student pilot flying from Pennsylvania to North Carolina, before it turned away from the national landmarks. The pilots were released without criminal charges being brought against them. The incident, which lasted about 45 minutes, sparked a frenzy of activity that tested the capital's post-Sept. 11 response system. Homeland Security officials said the defense system worked as designed. City officials, however, said they weren't notified of the alert until the all-clear sounded.

Investigators are still looking for a motive.

Scientists sent the new driving directions to Opportunity on Wednesday, commanding it to start inching down from the dune in a series of "mini-drives."
