The landmark London Eye broke down last night stranding visitors for up to four hours.
Roughly 500 people were left hanging after what the operating company, Merlin Entertainment, described as "a technical issue". They added that "at no point was anyone at risk".

The company released a statement outlining how a guest "made contact with the emergency services. Both the London Fire Brigade and the London Ambulance Service were dispatched but no action was required".
Merlin Entertainment also own and operate the Alton Towers theme park as well as Thorpe Park, Chessington World of Adventures, Madame Tussaud's wax museum and Legoland.
The company was recently fined £5 million over a rollercoaster crash in 2015 which left five people with life-changing injuries and others badly hurt.

A judge in the case criticised safety procedures at the company describing them as "woefully inadequate".
In response the company said: "We have learned every lesson from what happened last year and made a number of technical and procedural improvements to make sure an accident like this cannot happen again."
