Hundreds of sightseers were trapped on the London Eye when it was forced to stop turning for urgent repairs.
Wheel was forced to stop turningAround 400 people spent an hour stuck in capsules - suspended up to 450ft high - at the South Bank attraction.
Staff spoke to them via an intercom, instructing them to open emergency supplies of water, blankets and commodes.
Operators had spotted a technical hitch with one of the four tyres used to turn the giant wheel at about 6.10pm.
Each rotation usually takes about 30 minutes, but it took engineers more than an hour to remove the faulty part.
The wheel then continued as normal with its three other tyres.
London Eye spokeswoman Liz Edwards said: "We had two-way communication with all the guests, so we spoke to everyone to reassure them.
"There was a technical fault with one of the tyres so we thought the best thing to do was stop the wheel until it could be repaired.
"Engineers came along and the guests opened comfort packs with water, blankets and glucose tablets. There were commodes as well."
All the guests were offered warm drinks and a refund just after 7pm when they came down from the wheel
