Boeing's 787 Dreamliner got off to a rough start. Just over a year after its first commercial flight, the aircraft was grounded after batteries overheated on two flights. This Dreamliner, built for Air India, was the first produced at Boeing's new production facilities in North Charleston, South Carolina.

Aviation safety regulators have approved Boeing's battery fixes, and Dreamliners have started to fly again. Earlier this year, this All Nippon Airways 787 made an emergency landing because of battery troubles. ANA plans to resume commercial Dreamliner flights in June.

A LOT Polish Airlines 787, with a redesigned lithium-ion battery system, performs a test flight in March at Paine Field in Everett, Washington. The Dreamliner's distinctive wings sweep back at 32 degrees.

United Airlines is the lone U.S. carrier flying the Dreamliner. These are Business First Class seats on one of United's six 787s.

The use of composite materials on the Dreamliner makes larger window cutouts possible. Composites have replaced aluminum as the predominant material in the 787. The 777 is made up of 50% aluminum and 12% composites, compared with the Dreamliner's nearly 50% makeup of composites and just 20% aluminum.

A Boeing Dreamliner is held in Tokyo after problem with power supply
Problem is fourth mechanical incident for a Dreamliner in 10 days
On Monday, issue with brake indicator diverted plane
Boeing: "We know it will continue to receive heightened attention."

(CNN) -- An All Nippon Airways 787 Dreamliner was held in Tokyo after a mechanical problem, the fourth such incident for Dreamliners in 10 days.
The plane was delayed Thursday after a cockpit message indicated a problem with the power supply to its air-conditioning system.
More than 100 passengers who were supposed to fly to Frankfurt departed on a different plane eight hours after the scheduled departure time, ANA said.
Earlier this week, a Denver-bound United Airlines Dreamliner was diverted back to Houston after a problem with its brake indicator.
A week before, two United Dreamliners made unscheduled landings.

The Dreamliner can do THAT?

The Dreamliner can do THAT?

A flight from Denver to Tokyo was diverted to Seattle because of an indicated problem with its oil filter.
And a Houston-bound flight from London made an unscheduled landing at Newark's Liberty International Airport due to a "low oil indication."
In each case, the plane landed without incident and with no passenger injuries, Boeing said.
The incidents come six months after the Federal Aviation Administration and other officials grounded the Dreamliner worldwide due to troubles with its battery system.
"The 787 is a great airplane and we know it will continue to receive heightened attention when reliability events occur in service," Boeing spokesperson Yvonne Leach said Sunday.
Additional Dreamliners
The 787 Dreamliner began service in the U.S. in 2012.
The entire global fleet of 50 Dreamliners was grounded in January after two battery overheating incidents triggered concerns among safety officials.
Among the Dreamliner's innovative designs is a battery system that uses new, lightweight lithium-ion batteries.
In April, the FAA ordered all 787 operators to make specific modifications. United has been flying its fleet of six 787s since May 20.
United is the sole U.S. operator of the airplane, which boasts high fuel efficiency due to the lightweight carbon-composite materials used in its wings and fuselage.
In an apparent show of confidence in the new airliner, United announced Tuesday that it's ordering 20 additional Dreamliners, specifically the 787-10 model, a longer version of the plane.
The plane represents a new generation of efficient wide-body, long-range aircraft, helping to make it among the world's most heavily scrutinized aircraft.
Airlines worldwide have committed to buying the plane, and hundreds of millions of dollars are riding on Dreamliner's success.
On June 14, Boeing rival Airbus flew a similar airliner, its highly anticipated A350 XWB, for the first time at its facility in Toulouse, France.
