how a pilot would think gliding in dead stick
But it seems they didn't think of gliding it in - they appear to have set up a dirty dive for the localiser at or near the RioNegro VOR as though they were intending a standard 3' approach and continued in this full drag config even as engines failed and they squandered life saving height - so much height that they could still have reached the field even as the first engine failed if only they'd been at min clean sped and gear up.
