Weedhopper of Utah JC-35 Rocket

On 27 October 1981, John was killed in one of his own prototypes, the JC-35 Rocket, and on 30 December the following year the company filed bankruptcy papers. However, this does not necessarily signify the end of the company as John's widow, Susan Boman, continued as company president, following a reorganisation which has cut the range to just one model, the JC-24C.
