Would the airplane parachute be scalable to large commercial jets? I assume the fuel costs of carrying the extra parachute weight are too great but curious about the engineering.

Nobody has made a parachute remotely large enough. The engineering challenges are quite unknown.

I suspect the parachute would be far too heavy. Also, jets fly very fast, and the jerk when the chute opens would likely rip things apart.
