'I need to be home': Thousands of travellers stranded as fires shuts UK's Heathrow

Thousands of travellers stranded by a huge fire near London's Heathrow, Europe's busiest airport, scrambled to find ways to get home and reunite with their families on Friday as they faced what could be days of disruptions. Heathrow was shut as around 70 firefighters sought to put down the blaze at a nearby electrical substation in the west of London that knocked out power at the airport as well as the area's back-up power system.
