The WSJ details:
The U.S. trade deficit contracted sharply in July, posting its biggest drop in 17 months as exports of airplanes surged and U.S. demand for imports fell across the board.
The U.S. deficit in international trade of goods and services narrowed by 14% to $42.78 billion from a downwardly revised $49.76 billion the month before, the Commerce Department said Thursday. The June trade gap was originally reported as $49.90 billion.
U.S. exports expanded 1.8% to $153.33 billion, the highest level since August 2008, from $150.57 billion in June. Imports registered their biggest decline since February of last year, falling 2.1% to $196.11 billion from $200.33 billion in June.
