Those planes that drop water out the bottom...

[Yachtworker]

I'm sorry but I have no idea of what they are called and equally sorry for the quality of the photos, but I was down in La Ciotat for work today and 3 of these were doing circuits all morning, obviously training for summer, but best to be ready as there has been no rain for weeks and it was already 17 dgrees today!







they were dumping all the water 30 seconds after leaving the water but were doing it for hours.
