Adelir Antônio de Carli

De Carli's goal for the cluster ballooning exercise was to break the 19-hour flight record and claim a new world record. His first attempt was on 13 January 2008, during which de Carli successfully completed a four-hour flight from Ampére, Paraná, Brazil, to San Antonio, Misiones, Argentina over a total distance of 25 kilometres (16 mi). Using 600 balloons, de Carli reportedly reached heights of 5,300 metres (17,400 ft).

On April 20, 2008, after taking off in a chair attached to 1,000 balloons, Carli reached an altitude of 6,000 metres (19,700 ft) before losing contact with authorities. Pieces of balloon were later reported floating in the sea off the coast.

On July 4, 2008, the lower half of a human body was found floating on the ocean surface by an offshore oil rig support vessel about 100 km (62 mi) from Macaé. After the remains were initially identified from the clothing as those belonging to Carli, DNA tests confirmed they were his on July 29, 2008 after a comparison was made with DNA samples from Carli's brother.

In 2006, de Carli denounced human rights violations against homeless people in Paranaguá. These denunciations caused seven Municipal Guard agents and the municipal security secretary to be arrested.

Adelir Antônio de Carli (Pelotas, Rio Grande do Sul, Brazil, February 8, 1966 – April 20, 2008), also known in Brazil as Padre Baloeiro or Padre do Balão ("Balloon Priest" in Portuguese), was a Brazilian Catholic priest, who died during an attempt at cluster ballooning on April 20, 2008. Carli, an experienced skydiver, undertook the exercise in order to raise money to fund a spiritual rest area for truck drivers in the Paraná port city of Paranaguá.
