A National Transportation Safety Board report released Thursday says the pilot dumped about 350 gallons (1,325 liters) of pink water from the aircraft, which then stalled and crashed.
He told officials that he was manoeuvring at a low altitude when the plane "got too slow", causing it to aerodynamically stall before crashing.More news: Kem Sokha: Cambodian opposition leader freed from house arrest

A Federal Aviation Administration inspector also reported that there were two people aboard the single seat plane.
The Pilot-Raj Horan allegedly was conducting "a gender reveal flight for a friend".
Last year, an Arizona man was ordered to pay more than $8-million in restitution after an exploding target that was part of a gender-reveal stunt sparked a wildfire that burned almost 47,000 acres. In line with a report from the Nationwide Transportation Security Board, the airplane was created to hold only one particular person.
