I suppose if you have a serious problem, you do whatever you can to get down.

I've often wondered about this, most people have done the "falling leaf" exercise at some point, where you stall and hold it stalled for say 30 seconds or more. Now if you look at the VSI you see you're only coming down at 2000ish fpm, which equates to <30 miles per hour vertical speed. Better still, your forward velocity is pretty low. Last time I simulated an EF in an Arrow, leaving the prop forward, we were coming down at 1500 fpm with a forward velocity of around 75kts.

So in the event of engine failure, without any options for a safe landing, why not stall the thing, and "float" down onto something soft, rather than hit a fence with a high forward velocity?
