If you're ever in Bristol, it's well worth paying a visit to the Industrial Museum located in a former warehouse on the city's very scenic waterfront (check ahead for opening times -they may be undergoing renovations at this time). It's full of cool and memorable artifacts of Bristol's great industrial and maritime past. Included in the collection is a beautiful Bristol Sycamore helicopter. It's larger than an EC135 and weighs only slightly less, but it is powered by a single 550hp (!) engine. Makes you appreciate your modern engine power...
