A gender reveal stunt in the party town of Cancun, in Mexico, has ended in tragedy with two people dying.
Vision shared on social media of the moment shows a plane flying overhead as it reveals a sign declaring the expectant couple were having a baby girl.
Delighted cheers could be heard from a group filming the moment from a boat below.
"A girl, a girl," one person shouts.
Seconds later the plane swoops down as it turns away from the boat before nosediving into the water below.
Those on the boat can be heard shrieking.
The Cessna-type aircraft disappeared under the waves as the person recording the stunt says: "This can't be happening."
Local media varied in reports of how many people were on board the plane.
But two people believed to be the pilot and co-pilot later died after the aircraft crashed into a lagoon near the Caribbean Sea on Tuesday (local time), local media reported.
According to Mexican outlet La Prensa Latina, one of the pilots died during the rescue effort while the other died as paramedics provided first aid.
Members of the armed forces, national guard, police and paramedics attended the scene, but one person died while the rescue efforts by first responders were being carried out, Francisco Fernández Millán, president of the Nautical Association of Quintana Roo, said in a statement.
Photos showed bodies under white sheets being carried onto land.
The trend of elaborate – and sometimes dangerous – gender reveal parties has increasingly made headlines in recent years when the stunts have not gone to plan.
A New York man died in February when a device he was making for a gender reveal party exploded and killed him, while a Michigan man died in a similar explosion-related accident, also at a gathering, in the same month.
Closer to home, an Adelaide couple saw their car go up in flames in 2018 when a gender reveal burnout went wrong.
