BOSTON, Mass. (WUSA9) -- Our team has just landed here in Boston as we begin to report on the tragic explosions at the Boston Marathon. The people that we've spoken to here still seem to be in a state of disbelief, trying to understand what happened earlier this afternoon. "How could someone be so mean," Reporter Bruce Leshan heard a flight attendant on our plane say. "The Boston Marathon will never be the same," One Boston man returning home from D.C. also commented. Attached above are photos from Boylston Street, which remained closed by police when we arrived.
