Thud and Blunder, I'm sure that Charlie Zimmerman's Bo105 display in 1977 was exciting, but most of them (including this one) are not, especially from the crowd line. As helo pilots, we all appreciate the superb flying techniques and skills that go into these displays, but Joe Public usually doesn't. Anyway, in the meantime does this mean we have to wait another 28 years for the next interesting helo display?
