### Flight of UH  
#### 3.1.1 Time and Status  
The UH flight carrying the RBC solution samples took place on 6 November 2020 from the coast of Sasebo City to Arikawa Port in Shinkamigoto Town. The return flight was on the following day (Table 1).

Figure 4 shows the aircraft before take-off from Sasebo on its outward journey. The cruise flight took place as planned at an altitude of 100 m.  
RBC #3-1, which was sandwiched by Constar IIs in box A, was placed in the back row, #1-1 and 1-2 in the ATR700 were placed in the middle, and #5-2, which was sandwiched by type IIIs in box B, was placed on the right side of the front row close to the exhaust muffler. They were on a boat-like platform as shown. All the cargo on the platform was secured with rubber nets to prevent movement. The photo was taken at 9:45 on November 6.  
We monitored the outbound flight in Sasebo. The actual take-off and landing were performed by local pilots under visual observation. During the cruise, the flight was

simultaneously monitored at JL and at Sasebo and Arikawa ports. Figure 5 shows UH flight management, including the airspeed of UH of approximately 15 m/s, engine revolution per minute of 6000, and flight direction of approximately 260 degrees.  
The flight time was different between the outward and return trips, mostly due to the wind speed and direction.  
The containers for the RBC solution on the platform that [PERSON] was hanging from remained intact.  
The flight time was different on the outward and return trips. Due to government approval, the airspeed on the return trip was limited to 72 km/h or less, so there was no way to recover from the wind-induced slowdown on the return trip. Figure 5 shows a copy of the actual screen at the Japan Airlines headquarters and an image of the monitor at take-off and landing points.

This shows the outline of the flight path in the flight application and how the actual flight was conducted. The flight distance was approximately 55 km one way; (**B**) The flight from Sasebo to Arikawa port on 6 November 2020. The airspeed of UH was approximately 15 m/s (54 km/h), the engine revolution was 6000 per minute, and the flight direction was approximately 260 degrees.
