The alternative, if you rewatch Temple of Doom's mine car chase, or the bit where they leap out of the plane in the raft and skid down the mountain, is to superimpose them onto blatantly obvious fake backgrounRAB...
Even in Last Crusade there was some of this going on, the bi-plane sequence especially, both in the air, and when they are being chased down the tunnel by the German plane...
Looks terrible...
