it's bloody frustrating that these accidents keep happening! Especially when there is relatively cheap technology out there that would help prevent it!
I can think of two very cheap technologies that prevent these accidents:
1. See and be seen
2. Listen to (and use) the damn radio!
It's not rocket science...
I thought the comment by Flight Training Manawatu chief executive Michael Bryant that "occasionally these things will happen" was particularly foolish... no, they don't Michael, if you train and supervise properly...
