Very sad news, followed his battles with Craig Bredlove for the record when I was a kid, the Green Monster was always my favourite, always looked industrial 30's art deco, compared with the pretty 60's Spirit of America.
Probably last of the barnyard engineers, following in the tracks of the early pioneers of the car and plane, the likes of which we will never see again.
There was a great documentery on, I think channel 5, earier this year which covered the Land Speed record, Art was on the programme, still tinkering with jet engines in his barn.
RIP
