A gender reveal party took a tragic turn Tuesday when a plane crashed into the Caribbean Sea.

In the Nichupte Lagoon off the coast Cancun, Mexico, a family hired a private plane rented from a company called Xomex to reveal the gender of the expecting couple's child. While they watched safely from their booked boat, the Cessna-type aircraft performed stunts overhead with an "It's a girl" banner attached.

You can hear onlookers cheering in the recorded video of the incident. According to Queerty, one person jokes in Spanish, "It’s all good as long as it doesn’t end up crashing into us."

Seconds later, the plane nosedived into the water. 

The navy arrived on the scene for the rescue operation. The pilot and co-pilot both died on the scene, one during the rescue and the other declared dead while receiving first aid on land. The cause of the crash is being investigated.

Gender reveal parties have been a regular source of controversy in the last few years. In February of this year, an expecting father lost his life in an explosion of the device that was supposed to reveal his child's gender. One in Arkansas started a 47,000-acre wildfire that caused more than $8 million of damage.

We believe the tradition to be outdated since it places children in a binary box before they're even born, but if you're going to have a gender reveal party, keep it simple and cut a cake or something.
