Sorry if this has already been stated but everyone on this thread is going on and on about 'what if s' and '35ft lower' etc etc. The minimum limits for displaying (100' agl) have a built in safety margin for error. Obviously the aim is not to bust these limits but it happens. Can anyone who flies military ac at low level honestly say they have never had the rad-alt warner go off?? If you have then you too have bust a limit. But thats why the limits are there to allow for a margin of error - otherwise the published limits would be 0ft!! Cut the guy some slack - he (may or may not have) made an error that put the ac close to the ground - at the speed he was descending it may only have been a fraction of an inch of stick pull - but most importantly (especially for him and his family) he didn't pile in. End of story.
