According to the media reports an R44 Raven ll aparently exploded in mid air and crashed at Tocumen International airport killing all three on board. From the photos it looks unlikely to be an airborn explosion as it seems to be a small impact area, and what the heck would cause an R44 to explode mid air? Apparently the pilot reported mechanical problems and asked to land at the airport, they were returning from the Darien. I new one of those onboard... RIP
