Marty, I'd say no time. I've found the spot it landed on Google Earth and it's not much more than 3klm from the end of the runway. On the Baza site, there's two lots of in-cabin footage, one of the lift off and birdstrike, the other of the landing in the cornfield. I'd say there's very little missing footage between those clips. A lot of luck with timing and terrain. If they were in the air another ten seconds it could have got a bit messy.
I put a red dot on the satellite screen grab where it landed. That line with some trees that the plane crossed is actually quite a substantial irrigation channel full of water.
