Mrs. Lemuria and her daughter Daisy took a HSK flight from the Spring City of State A to the Atlantis Island of State B for a holiday. Spring City is their permanent residence. It was Daisy's first time to travel by plane. The flight was planned to depart at 10:10am. Mrs. Lemuria and Miss Daisy arrived at the check-in desk at 8:30am and checked their luggage. They had two pieces of check-in luggage and on one piece of carry-on baggage. At 9:00am, they got their boarding pass and luggage claim slips. Later on, passengers were announced that the flight was delayed because of the temporary flight restriction from Air Traffic Control Bureau of State A. Passengers waited in the terminal building for more than 60 minutes. At 11:30am, the plane took off. During the flight, there was severe turbulence at about 13:30pm. Because of the first experience to flight, Miss Daisy was very scared and even had a physiological reaction of nausea. When the turbulence was over and the plane was flying smoothly, Mrs. Lemuria got up and went to the restroom. However, she got tripped by the passenger named Carlos in the front row, who stretched his legs out in the aisle to rest. At that time, Mrs. Lemuria had a bruised knee and a swollen ankle. Her daughter was frightened again and screamed for a while. The flight attendant immediately bandaged Mrs. Lemuria's knee and reduced swelling on her ankle, and Carlos apologized for his behavior. After getting off the plane, Mrs. Lemuria and her daughter went to the luggage claim area. Unfortunately, their one piece of check-in luggage was lost. It never rains but it pours. Mrs. Lemuria's ankle had already swollen so badly and she had a terrible pain. So she and her daughter went to the William hospital on the Atlantis Island. Thesurgeon there diagnosed that Mrs. Lemuria got a fracture of her ankle and a bruised knee. Consequently, a series of treatment costs incurred.
