He, to begin with, went round the technically updated wind-solar power station of the unit to learn in detail about its operation.

Feasting his eyes on the wind-power generator and solar panels in many rows, he said that still fresh in his memory was his visit to the station accompanying leader Kim Jong Il in November 2011.

The wind-solar power station of the unit is the legacy of Kim Jong Il and the electric wires extending from the electric transmission network reflect loving care and warm solicitude bestowed by him upon airpersons, he said.

The natural power station of the unit is an electricity production base and, at the same time, a base for education as it conveys the benevolence of Kim Jong Il who spared nothing for airpersons, he noted, stressing the need to spruce up the power station associated with the loving care of Kim Jong Il and meticulously organize the work for putting its operation on a normal footing so that his leadership exploits may be glorified for eternity.

Saying he was very pleased to see the nice power station, he highly praised KPA Unit 6556 and officials, scientists and technicians of the State Academy of Sciences for making a positive contribution to successfully constructing the station to be proud of through army-people coordinated operation. He extended thanks to them.

It is important to conduct a dynamic drive to widely use natural energy including wind, solar ray and geotherm in order to solve the electricity problem of the country, he said, before indicating tasks and ways to do so.

Then he inspected the unit.

He went round the monument to on-the-spot guidance of the peerlessly great persons of Mt. Paektu and the service personnel's hall.

President Kim Il Sung and Kim Jong Il, with deep insight into the position and importance of the air force in defending of the country, devoted everything to the development of the air force, Kim Jong Un said, adding that the course of development of the air force of Juche is the history of leadership provided by them with tireless devotion and great efforts.

Praising the unit for building the hall as intended by the Workers' Party of Korea, he said, underlining the need to intensify the education in the greatness of the leaders, Kim Jong Il's patriotism, faith, anti-imperialist class education and moral education in order to fully prepare the airpersons as death-defying corps in the sky. The short-cut to preparing the KPA as the invincible revolutionary Paektusan army is to take hold on the four strategic lines, three tasks and five-point education for bolstering up military muscle indicated by the party as the three major thrusts, he added.

To build well the units associated with the leadership history of the President and Kim Jong Il and add eternal brilliance to their undying exploits should be a starting point and beginning of all affairs in the KPA including military and political affairs and supply service and then it is possible to turn the KPA into the strongest army in the idea and faith, he noted.

He went round the flight drill room of the unit and flying lecture room of the Second Squadron to learn in detail about the combat and political training.

Watching the airpersons skillfully controlling the equipment for piloting with the help of computers, he said it is good to have a lot of such drills and it is important to undergo effective training, while letting all airpersons to increase requirements for properly keeping their positions in the air. He gave an instruction to further modernize the drill equipment.

He said that in order to prepare the airpersons to successfully perform their combat mission any time and under any unfavorable circumstances through drills, it is necessary to arrange well the hall of flight drill in all flying units and steadily raise the quality of the drill.

He went round bedrooms of the airpersons, washroom, bean store, mess hall, kitchen, greenhouse and mushroom cultivation room to take warm care of the living of the airpersons with paternal love.

On this day he looked round fighters of the unit including fighter No. 109 seen by the President.

He stressed that the Air Force should take the lead in defending the country during the days of battles by managing in a more responsible manner the fighters associated with leadership exploits of the President and Kim Jong Il.

He had a photo session with combat pilots and other service personnel after expressing belief that airpersons of the unit would undergo intensive trainings to be always combat ready under the slogan "We wait for only the party's order for sorties!" so that they may be ready to fly once an order is issued by the Party Central Committee.

Before leaving, he asked commanding officers of the unit to convey the cosmetics and foodstuff he had brought with him to airpersons' wives as well as his congratulations to them on the March 8 International Women's Day.

He was accompanied by Hwang Pyong So, Jo Kyong Chol, Ri Pyong Chol and Son Chol Ju.
