Quick update. I have spoken with and e-mailed the Univ. Texas aviation archivist regarding the 2 folders that Dave C posted. As I said earlier, the archivist told me it is a minimum of a 4 week wait.
Dave C. You asked about the source of the photo I posted. That is a good question. The Packard historian that I thought sent it to me claims he is not the source. I did some more searching and it seems the (late) Robert Neal had the photo in his collection. Robert was the author of the definitive work, Packard – Master Motor Builder. Robert’s photo may be the original (see attached) as it shows more of the Packard Proving Grounds. I would dare say that the photo I first posted is cropped from that original print.
BTW, the Packard Proving Grounds were opened June 14, 1928. So with the PPG fairly new and the DR-980 new, it seems to me that Packard would have arranged a flight of the Mooney A-1 over the PPG for a photo op.
This MAY be the only known photo of the A-1 model. Has anybody seen another photo of this airplane?
As pilots, you folks may enjoy reading the starting sequence by Walter Lees, Packard Test Pilot:
From Jo Cooper's book PIONEER PILOT:
“I made the first test in a Stinson, a cabin job, the SM-IDX "Detroiter". The official test flight was to be in the morning, but Captain Woolson and I took the plane up the evening before just to be sure. The engine had only one valve which acted as intake and exhaust. Our first test engine did not even have short exhaust stacks, but exhausted directly out of the cylinder into the open air.
It flew all right, but coming in to land, I couldn't throttle under 1500, so took off again. In my next attempt at landing, I lined up the plane on a glide to the field, then cut the fuel off entirely and landed with a dead stick. The next day I made several flights. Capt. Woolson had installed a revolving valve on the intake and exhaust ports. It was hooked to the throttle so that it was open for takeoff and flying, but then closed off the ports and put back suction in the cylinders so the engine would slow down when landing.
I made many experimental flights with Capt. Woolson, also with mechanics. Once we made a flight to 19,000 feet without oxygen. We also made several night flights with automobile headlights for landing lights. While flying one day, Capt. Woolson confided to me that he someday wanted to make an engine with one moving part.
To start the engine in cold weather, we heated each cylinder with a blow torch, then ran the engine to warm it up. The flying was done inside the Packard Proving grounds, approximately 3/4 mile long and 1/4 mile wide. There was a hangar at one end.
To impress the visitors who came out to see the engine run and fly, in winter time Capt. Woolson would call me up from the plant in Detroit, telling me the approximate time he and the visitors would reach the Proving Grounds. We would warm the engine up in the hangar and keep it running until we saw the car with the Capt. and the visitors turn into the grounds. Then we would shut the engine off and when they arrived, push the plane outside and start the engine before they could inspect it and see it was already warm.
The first starter was a shot gun. Later, it was replaced by a special electrical starter. We also installed glow plugs in the head of each cylinder, hooked up directly to a large battery. When the push button for the starter was depressed, contact with the glow plugs was made. At no time was gasoline used to start the engine.”
