The quest for high level, wide angle (RC9) photography (and in colour) began, in Adastra's case, in early 1973 following a suggestion from the National Mapping Council, (per Joe Lines). The only 40,000 foot capable aircraft within Adastra's financial reach was the Hawker Siddeley HS125. We requested from Qantas and were given relevant performance figures. We were also able to put the tape measure over a Qantas HS125 with regard to the physical fitting of the RC9 camera, (Jack McDonald, our works manager, in charge).

Then in June of 1973, we learnt of an HS125 being on the market. This was VH-TOM which belonged to a large wholesale grocer "Tom the Cheap" and which was operating out of Perth. Consequently I went over to Perth and was given a demo flight on 23rd June 1973. (Max Garroway, who had been one of Adastra's top survey pilots, agreed to accompany me on the flight. Max had resigned some years earlier and was now the W.A. manager for Michelin.)

Before the flight I had given the pilot, a young man named Barclay Archbold, our requirements for survey operation - mainly to take-off with full fuel and flight at 40,000 feet true. Before the flight Barclay was straightforward and told us that, under the conditions requested, we would be disappointed with the aircraft's performance. And so it proved to be. The HS125 with full fuel climbed magnificently to 40,000, but as a survey platform at that weight, was hopeless. It actually wallowed. Barclay then agreed to my request and we stooged around until we could ascertain the fuel limitation to enable stable flight at that height.

In spite of this setback (we would be losing about 30 minutes duration) it was decided to press on with the investigation. To this end, East-West Airlines, who were about to take-over Adastra, fabricated a light weight pattern of the RC9, and David Ham of Qantas designed a cradle for the camera and its fitment in the rear of the HS125.

However, physical problems with the latter continued and Qantas suggested switching to the Boeing 707 for the test programme. David Ham showed that the RC9 could be fitted in a fuselage panel immediately below the cockpit. This panel gave access to a pressurised compartment which could also be reached from the navigator's station, behind the captain's seat. The aircraft chosen for the modification was VH-EAA and the camera installation was made without problem.

Our first test took place on 20th December 1973. VH-EAA was on acceptance after a major, and takeoff and landing were both at Mascot. The weather turned sour during the flight and we ended up over 8/8, so my only job was to go through the routine of setting up the camera (i.e. drift, time interval, level) and making sure the on/off was working. This switch operated by way of an extension lead which I held in the cockpit.

The flight could have been termed a fizzer but at least the ground work (literally) had been proven, and all we awaited was another opportunity both weather-wise and a suitable VH-EAA flight.

Costing, as always, was a major consideration and although N.M.C. maintained their interest, no contract would be made until Adastra had produced a sample run. Chartering a 707 was out of the question, but to help out, Qantas now suggested an economical way of achieving our aim. Periodically EAA ferried crews to Avalon for training and we were offered a block of time during the ferry, for our work at 40,000 feet.

However, before a second opportunity arose, EWA, now the owners of Adastra, seemed to lose interest in the project. There was also a further small contretemps in that Adastra and I parted company in May 1974.

Lou Pares, our General Manager, was overseas and in his absence, being his deputy, I was in charge, but sadly had a serious run-in with John Riley, the G.M. of EWA. The latter were, no doubt, dab hands at moving passengers and freight around the countryside, but knew precious little about air survey. Anyway, my dispute with their top man was enough to give doubts about the future and I resigned.

Pares, on his return, was determined to regenerate the project and asked me to act as standby consultant and navigator. This I agreed to readily, as I was as interested as he.

But it was late in the year before the scheme got underway again, and no Qantas ferries coincided with survey weather until January 1975, when the first trial since December 1973 occurred. The flight was moderately successful in that we had produced survey photography at 40,000 feet. However, the quality of the prints was substandard, and adjustments to aperture, exposure time, filter and camera heating were required.

Then over the year another five flights were made with little achieved (mainly due to a series of camera faults or poor weather) until the last on 11th November 1975, when good quality survey photography resulted. My records of the seven sorties are rather scant but below are listed such details as I retained.

Some Comments on the 11th November Flight:

Postscript:

All our work with its attendant delays and frustrations, was for nought, as shortly after that last and successful flight, satellite imagery became readily available.
