BTW, yes the wind speed does increase with height.
A great deal and very quickly.
Which is why when you are flying a kite, you can get it to stay up fairly easily once you get it high enough.
Thanks metmom. So would the danger be that you could be blown out the window? Again, if you lay on the floor up against the far wall or in a hall even of the high rise......it might be ok. No? Just hold on to something and ride it out?
