PLANS to build a cable car linking the Royal Docks with North Greenwich pose an “extremely low risk”, a safety review has concluded.

Opponents of London City Airport expansion wrote to Mayor Boris Johnson, warning the link would pass through the airport’s public safety zone, possibly putting passengers at risk.

As a result, Transport for London ordered the National Air Traffic Service to carry out a safety probe.

And in a statement issued today, TfL said: “Even considering expansion of City Airport, the probability of an aircraft accident affecting the London cable car would be less than one incident every 15 million years.

“This was an extremely low risk and well within safety guidelines.”
