19. SOUNDBITE: (English) Kelly Matthews, British Airways London Eye Press Officer:
"We're fairly hopeful that we'll open later today. On a normal day the London Eye opens until 10 o'clock at night, so there's enough time for the temperatures to drop, for things to settle down a bit and for people to come back."

London sweltered through its hottest day on record on Wednesday as a heatwave caused more trouble for British travellers, forcing heat-related speed restrictions on train lines for the third day in a row.
Tourists and Londoners tried to beat the heat in the British capital as temperatures in central London soared to a record high of 35.4 degrees Celsius (95.7 Fahrenheit), according to the state weather service.
The previous record for London was 35 degrees Celsius (95 Fahrenheit), set in 1990.
Some people cooled off in the fountain at Trafalgar Square, while others decided to sweat it out in a bid to get a tan.
Meanwhile at the London Eye, a giant big wheel giving views across the city, many tourists were disappointed after the popular attraction was shut down for the afternoon due to the sizzling heat.
London Eye spokeswoman Kelly Matthews said the pods on the observational wheel were in danger of becoming too hot.
She said that although the temperatures had not reached the 30C maximum, it was decided to close the attraction for the comfort of visitors.
Matthews said she hoped the attraction would re-open on Wednesday evening or Thursday.
