LONDON — The first flight has landed at London’s Heathrow Airport – Europe’s busiest hub – since airspace across the continent was closed by ash spewed from a volcano in Iceland.

Many European flights took to the skies today as airports slowly reopened, but the travel chaos was far from over: A massive flight backlog was growing and scientists feared yet another eruption.

A flight from Vancouver landed at London’s Heathrow shortly before 4 p.m. (EDT) – the first since flight paths were closed after Iceland’s Eyjafjallajokull (ay-yah-FYAH’-plah-yer-kuh-duhl) volcano erupted Wednesday.

British Airways said it hoped about 24 other flights bound from the United States, Africa and Asia would land later Tuesday at Heathrow.
