PPRuNe Forums - Heikkis' Silhouette Challenge

Just a curious question having observed, but not taken part in these threads over the last decade or so, who or what is "Heikkis' " ?? I've looked back, but there never seemed to be any posts with that name. Just curious tis all ;-)

There is a professor Heikki Kalviainen who has done much on Pattern Recognition and Image Analysis.
But that might be pure coincidence.

Lake Buccaneer per chance?

It's not Lake Buccaneer. Check the tailplane position.

Re SHJs question (#11700) my post #10830 of 24th Oct 2012 may provide a clue. Ned

The challenge was American and only one was built.

David Thurston involved?

Referring back to the Harlow, it seemed familiar and I think I saw one at Oshkosh. The name that sprang to mind was incorrect!

No involvement by David Thurston.

Clues are required I feel. This should help.

Looks like something from the Mad Max.

I believe it is the Saunders Roe Skeeter Mk6 G-AMTZ fitted out as an air ambulance.

No John I did not find that photograph of the aircraft, but from the cockpit shape and nose wheel I thought it was possibly a skeeter with side litters and then found a side view of the aircraft. I understand the aircraft was fitted with a 200 hp Gipsy Major engine. I also understand the tank on top of the main rotor hub contained HighTest Peroxide for rocket booster system to the main rotor. That must have been a nightmare, good job the Bell turbocharged Sioux came along..

Here is the next:-

The two blokes in the litters are the pilot and observer when they tried it.
