blimey that is a clean break
so chaps - does aluminium get unseen stress cracks
I do know that they immerse aluminium aeroplane parts in a flourscent die to check for cracks
filmed them doing helicopter parts once

this is a bit worrying too

If I had been there as the mast came down I would have had the camera running
it would have been a good youtube film
