He also detailed the operation a little bit more: he was returning to the airfield from another bushfire when he saw the initial smoke column. He took the initiative to land and start the attack on his own since the fire was so close to houses. He made about 25 refills at the swimming pool, and this bucket carries about 600 liters, if I remember correctly. The swimming pool level lowered not even 40 cm after the mission. The helicopter left when the first firetruck arrived, the fire having already been extinguished.

消防車が到着するより前にヘリコプターが消火活動をしたようです。

バケツのようなものを吊したヘリが見事にプールの水を汲み上げて火災現場まで運んでいったそうです。このバケツ1杯で600リットルの水が運べるそうです。
