A British Airways Boeing 747-400, performing flight from Chicago O’Hare (USA) to London Heathrow (UK), was climbing out of Chicago when the crew requested to stop climb at 15,000 feet advising, they were unable to accelerate beyond 190 KIAS while working on a technical issue.

The crew advised no assistance was needed, they wanted to continue along the departure route. About 20 minutes later the aircraft was provided with delay vectors, the crew decided to return to Chicago advising they had not been able to retract the nose gear.

The aircraft landed safely on runway 10C about 1:50 hours after departure and taxied to the apron.

The aircraft remained on the ground for about 2 hours, then was able to depart again and reached London with a delay of 3:15 hours.
