A Ryanair Boeing 737 aircraft is parked on the tarmac at Orio al Serio Airport in Orio al Serio, Italy, under an overcast sky. The aircraft's forward left door is open, and a mobile airstair is positioned, with approximately 6-8 passengers, mostly wearing dark clothing and carrying backpacks, ascending the stairs to board. The aircraft's fuselage is white with a blue underside and a yellow stripe, displaying the blue "Ryanair" logo and partial harp emblem. The nose landing gear cover displays "HGZ". To the left of the aircraft's nose, a lone ground crew member, wearing a bright yellow high-visibility jacket, black balaclava, and black pants, stands facing right while looking at a smartphone held in both hands. A yellow ground power cable extends from the aircraft towards the left, passing near the ground crew member's feet. A white ground support unit is visible under the aircraft's nose. An orange safety cone is placed near the base of the airstair. The grey asphalt tarmac features yellow and white painted lines, a horizontal metal drainage grate, and a red and white painted line in the foreground. Distant buildings with red roofs and sparse trees are visible on the horizon under the hazy sky.
