A Gol airlines jet with around 150 people aboard is missing over the Brazilian Amazon after a midair collision with a smaller jet, Brazilian aviation authorities said. Five planes have been sent to search for the missing aircraft, Brazil's air force said.

"Hmm, we didn't didn't coordinate two planes and they crashed and we don't know why...let's send out five more, they'll be just fine.
