Kevin Page (TNT's Bum) plays one of the chopper medics in the above scene.
The opening two episodes of this season were aired as a feature length episode in 1987 on US TV and a couple of European countries. It was titled 'After The Fall' and later became 'Ewing Rise' and 'Digger Redux' in its two part episode form.
Along with the Ray and Jenna scene, there was another one with Bobby on the telephone in his car. These scenes are missing from the two part episodes. This isn't uncommon as the 1986 'Return To Camelot' feature length episode also had a few scenes missing in its two part syndicated DVD version.
