Just happened to surf this subject to see what it was about. Very Interesting that folks gave "spotters" those associative names.
I really never thought of it before as in the states its sort of quiet when it comes to spotting. I met the first ones who were from the UK down at Mojave California. I have been flying for over 35 years and these folks knew more about planes than I did. Type model etc. Very interesting.
Along those lines there are lots of folks in the states who hunt crashes. Now that interests me. We have a lot of planes that have never been found, in fact in California alone it appears many hundred.
I have some websites for Historical wrecks if someone wishes to PM for them or my email is good......
