Vision from the incident shows the two aircraft flying near-parallel when one clips the tail of the other, sending it flying directly up.

Both planes then entered an out-of-control spiral directed towards the ground.

Witnesses who rushed to the crash site also filmed flames running along the ground as thick black plumes of smoke rose from the wreckage.
