This made me smile this afternoon.
At the end of a climbing, descending and turning lesson I always demonstrate a power off/ clean stall so that the student knows what to expect during the next lesson. While pattering my way through the signs and then the symptoms of the stall my student very enthusiastically said, "Yeah, you can really smell it can't you". ???
??? I then pointed out that stalling was all about lift (or a lack of it) and that it would be a good idea for him to read chapter ten before his next lesson. I didn't like to ask what he could smell.
