The family of four people killed in the crash of a Marine Corps jet in a San Diego County neighborhood two years ago are suing the federal government and Boeing.

The lawsuit was filed Wednesday in U.S. District Court by Dong Yun Yoon, whose wife, two daughters and mother-in-law were killed in the December 2008 crash.

The suit accuses the military and Boeing, the aircraft's maker, of negligence and seeks unspecified damages.

The military says a series of bad decisions allowed the F-18 to go down in University City after an engine failure. The crash killed four people, destroyed two homes and damaged others.

After-hours calls made to Boeing on Wednesday were not immediately returned.
