I remember the tale of a Bf109 which was downed during WW2 - by an Avro Rota autogyro (or it could have been a Cierva C30).
Doing radar calibrations south of Portsmouth when the '109 jumped him thinking it would be an easy kill.
After trying to dodge him, the 109 dived on him, the autogyro pilot simply slowed right down very quickly and the '109 overshot him straight into the sea.

“A well known engagement involved a 2 AACU (Anti-Aircraft Co-operation Unit) ROC, L3085, and Plt Off D. H. Clarke, who had painted a red ‘Saint’ (the Leslie Charteris character) in a red-framed yellow diamond on each side of the rear fuselage of his ‘own’ Roc. On 26 September 1940 he was sent out to search for survivors in the water 15 miles (24 km) south-west of St Catherines Point. With Sergeant Hunt in the gun turret – which, unusually for 2 AACU Rocs, was fully armed – he took off in the late afternoon. As he instituted a square search in the area indicated, he noticed what he thought was a Swordfish also searching about 3 miles (5 km) away.After about 45 minutes of fruitless search in the gathering gloom, he suddenly noticed that the Swordfish, now only half a mile away, was in fact a twin engined floatplane. Out of curiosity, wondering what it was, he flew towards it: and then suddenly realised it was a Heinkel He 59, a German aircraft probably on the same air-sea rescue task as himself. Unsure as to whether he should open fire on an aircraft on such a humanitarian mission, he flew across its nose with Hunt training his turret at it.

As he did so the German nose gunner opened fire with his 7.9mm machine gun, and Hunt returned fire, his tracer pouring into the Heinkel’s fuselage. After the pandemonium and shock of his first action, Clarke swung on to a parallel course, and re-established communication with Hunt , whose intercom lead had been pulled out. The Heinkel turned for France, skimming the waves. Happily the twin engined bi-plane was even slower than the Roc, with a top speed at sea level of only 137 mph (220 kph), and Clarke was able to gain on his adversary; although he was still faced with the prospect of having to drop a wing to enable Hunt to open fire, even though his propeller was skimming the wave tops.

At 300 yards range he dropped a wing, and Hunt opened fire with another broadside. The Heinkel replied from all three gun positions, nose, dorsal and ventral, a single machine gun in each, but Clarke had to lift the wing after only a few seconds to avoid side-slipping into the sea, causing the last few rounds of Hunt’s burst to shoot harmlessly up into the air. The two aircraft continued these brief exchanges of fire for about 25 minutes, until the coast of France was looming up. Both aircraft were hit, and one of the Heinkel’s gunners stopped firing; but just as Clarke was about to turn away, the Roc was hit in the engine.

It faltered, and Clarke switched to the reserve 17 gal (77 ltr) tank, pulling up and away. Just as he thought he might have to ditch, the Perseus picked up, and he nursed the damaged aircraft back to Gosport. But before he could taxi in the engine stopped, out of fuel. Clarke claimed the Heinkel as ‘Damaged’.

On his return his groundcrew found two incendiary bullets in the main fuel tank, above which he sat. They had entered low down in the petrol, which had extinguished them; slightly higher, in the explosive fuel/air mixture above, and the Roc would have been ‘missing in action’. This action was almost certainly the nearest the Blackburn Roc ever came to destroying a German aircraft in combat”.

A Venezuelan Air Force F-16, piloted by Lt. Beltran Vielma, shoots down a rebel OV-10 Bronco near El Libertador Air Base during the second coup attempt of 1992, on November 27. Vielma used the M61 Vulcan cannon of his F-16 to destroy the light attack aircraft. The rebel pilot, Lt. Carlos Mictil, ejected safely and was arrested later. The Venezuelan coup attempts of 1992 were attempts to seize control of the government of Venezuela by the Hugo Chávez-led Revolutionary Bolivarian Movement-200. The first coup attempt took place on 4 February 1992, and was led by Chávez. A second coup attempt on 27 November 1992, took place while Chávez was in prison but was directed by a group of young military officers who were loyal to the Revolutionary Bolivarian Movement-200. On 27 November 1992, the OV-10s were widely used by mutinous officers who staged the second attempted coup against former President Carlos Andrés Pérez. The rebels dropped bombs and launched rockets against police and government buildings in Caracas. Four Broncos were lost during the uprising.
