Sad news.
I fortunate to be in the company of Mr Ackroyd briefly at Black Rock in September 1997. in the photo we are heading out to de-FOD the track. Ackroyd far right, Yours Truly third from right, Breedlove fifth from left, SoA in the background.
We found a number of large-caliber shells, some of them intact, and tossed them into a bucket
Ackroyd's book,
Jet Blast and The Hand of Fate is a fantastic read with many really interesting photos of his adventures with unlimited LSR vehicles, but also long-distance, high-altitude balloons. What a career!
