Seattle area residents have the Seafair airshow to look forward to this weekend, along with several I-90 bridge closings Thursday through Sunday to accomodate the Blue Angels. Following the crash and loss of Lt. Cmdr. Kevin Davis at an April airshow in South Carolina, the Blue Angels grounded themselves for 9 days and canceled a May appearance in Nebraska. They returned 3 weeks after the incident to perform in North Carolina on May 12. The solo position Davis held has been filled by a former member of the squad, one who holds a special fondness for Seafair. Lt. Cmdr. Craig Olson calls Kirkland, WA home and his local connection was always noted by the media in past appearances. The cause of the crash is still under investigation.
