Re: another factor
Like I said in my post about parachutes, they tend to move across the ground at the same speed as the wind (discounting steerable chutes that are unlikely to be used on a mission like this). If the wind is blowing at a couple hundred MPH, then the lander will be going very fast when it hits the surface. In that case, the airbags probably couldn't withstand the impact. I can state from personal experience -I used to be a paratrooper - that a landing doesn't get any softer when the wind is blowing.
