Heathrow said Saturday it had “added flights to today’s schedule to facilitate an extra 10,000 passengers.” British Airways, Heathrow’s biggest airline, said it expected to operate about 85% of its 600 scheduled flights at the airport Saturday.While many passengers managed to resume stalled journeys, others remained in limbo.

Laura Fritschie from Kansas City was on vacation with her family in Ireland when she learned that her father had died. On Saturday she was stranded at Heathrow after her BA flight to Chicago was canceled at the last minute.“I’m very frustrated,” she said. “This was my first big vacation with my kids since my husband died, and ... now this.

The fire was brought under control after seven hours, but the airport was shut for almost 18 hours. A handful of flights took off and landed late Friday.

There are two Lutheran churches in Nuuk. The Hans Egede Church is named for the Danish-Norwegian missionary who came to Greenland in 1721 with the aim of spreading Christianity, and who founded the capital city seven years later.A short distance away stands the cathedral, and next to it, a statue of Egede remains on a hill in the Old District. In recent years, the statue was vandalized, doused with red paint and marked with the word “decolonize.”

Egede’s legacy is divisive. Some credit him for helping educate the local population and spreading Lutheranism, which continues to unite many Greenlanders under rituals and tradition.But for some, Egede symbolizes the arrival of colonialism and the suppression of rich Inuit traditions and culture by Lutheran missionaries and Denmark’s rule.
