Authorities from Costa Rica stated on Saturday that a plane thought to have crashed there was carrying German businessman Rainer Schaller, who is well-known for his line of fitness facilities.

The founder of the McFit gym business in Germany, Schaller, and several of his family members were aboard the wreckage, according to Costa Rican officials who reported finding it earlier on Saturday around 17 miles (28 km) from Limon airport.

Schaller, 53, was traveling with other Germans including a 44-year-old woman, a 40-year-old man and two minors. The pilot, 66, was a Swiss citizen, according to Costa Rica’s security ministry.

Costa Rican authorities received an alert on Friday night about the missing plane, which was en route from Mexico to Limon, Security Minister Jorge Torres said earlier.

The aircraft had lost communication with the control tower near Barra de Parismina, a few minutes from Limon, according to Torres.
