GL: Whistle "diagram"

[Ken Bloomfield]

I have made a JPG sketch of the 1 and 2 whistle meeting/overtaking 
scenarios, and anyone who wants it is welcome.  Only 27K, so not an email 
hog.

Since it is not possible to imbed graphics in the list-serve, I have *tried* 
to use the normal ASC characters to simulate it.  I don't know if this will 
come through or not, but if it does, and the track lines that you should 
take don't get all fouled up, then this should settle the who sees who out 
what window on a "one whistle pass" and a "two whistle pass".

The track lines are for you.
