“The possibility was studied that there might be some unknown phenomenon at work⟳ that could cause a reduction in structural stiffness with age. Such a reduction in stiffness could result⟳ in a reduced flutter speed⟳ and lead⟳ to flutter. In 2004, Airbus conducted GVT in support⟳ of its MRTT program⟳. The testing was conducted on an aged A310 aircraft (MSN 523) that had accumulated over 28 000 flight hours. This test⟳ aircraft had the same design⟳ of VTP and rudder as the occurrence aircraft. GVT results found that fin bending and rudder rotation frequencies of the MRTT test⟳ aircraft were consistent with those obtained during the original A310-300 certification. No indication was found to suggest⟳ that stiffness had reduced with age.”

“"Oh, by the way, I heard of a rather good thing today, New Kleinfonteins; it's a gold mine in Rhodesia. If you'd like⟳ to have⟳ a flutter you might make⟳ a bit."”
