Boeing posted a 19 percent decline in second-quarter net income, reflecting charges related to delivery delays of its Airborne Early Warning & Control program. The defense contractor and aerospace company reported net income of $852 million, or $1.16 a share, down from $1.05 billion, or $1.35 a share, a year ago. Earlier this month, Boeing said its results would include a pretax charge of $250 million, or 22 cents a share, on delays at the international surveillance-jet program. The company expects to deliver the first two aircraft in July 2009, four months later than previously scheduled.
