While renting a Harley Davidson in Saint Helena, CA - I was sitting at Mike, the shop owner's old wooden desk in his open area office, when I glanced down and saw this picture under his glass. This surely must have been a site to see I said.
He then pointed out to his parking lot and I saw a pair of old radial engines all bolted down to engine test jigs and full throttle engine set-ups. He said, before COVID-19 hit , I used to run up these old babies all the time. One of the engines in the parking lot - ready to start was a 1,600 hp Wright Twin Cyclone engines.
He will start one of them up and run them for you for $100. If I wasn't in such a rush - I would have done it. You just never know when or where you bump into more Flying Boat history.

You just never know... Great to bump into history. Love the history of those Clipper days. Twin Cyclone engines... an incredible machine. And seeing you didn't have time for the run-up.... for only $1.50 https://www.youtube.com/watch?v=QR142psoNgM
$1.50 - What a bargain. Thank you Tom.
