Or was the volcanic ash just an excuse? Air Force One could have flown around the ash cloud even if it meant going half way around the world the other way.
From the article at the link below:
Polish President Lech Kaczynski and his wife, Maria, along with dozens of top Polish government officials were killed April 10 when their airplane went down in heavy fog after clipping a tree on approach to Smolensk, Russia.
Mr. Obama has not gone to the Polish Embassy in Washington since the accident, but Secretary of State Hillary Rodham Clinton and Vice President Joseph R. Biden Jr. both have. There, they signed a condolence book.
Instead of signing the condolence book at the Polish Embassy, Mr. Obama took off for the golf course.
Mr. Obama has played golf far more often than former President George W. Bush. In his eight years in office, Mr. Bush played just 24 times. His last time as president was Oct. 13, 2003.
It was the 32nd time Mr. Obama has played golf since taking office Jan. 20, 2009, according to CBS Radio's Mark Knoller.
