#1 Mick Mannock
#2 Chance Vought Pirate
#6 1475 hp Wright R-1820-80 engines, fully enclosed main wheels when retracted, semi-retracted tailwheel, taller more rectangular fin/rudder, 270 mph max speed vs 230, 2500 max range vs 2,125, operated almost exclusively by US Navy, most were rebuilds of R4D-6s
#7 AC47, AC130A
#8 Hughes 500 chopper
#9 Low Altitude Parachute Extraction System -- wherein a cargo pallet is snatched out the back of a flying transport plane (typically a Herc) at ground level

#5 "angle of attack" the vane tells you what it is

A shot in the dark would be the C-17 replaced the C-141  |

Here we go:
Patrick:
#1 and #2--nope--Mick Mannock flew SE-5s also.
#6--you got that one.
#7--there's one more
#8--Sort of. The OH-58 is also considered a Loach, more details please.
#9--you got this one also.
faif2d:
What's an angle of attack vane?? ;D
PropNuts got #10--the C-141 was just retired from active USAF service, though a few remain in the AF Reserve. They are indeed being replaced by the C-17.
Wayne--African, with a coconut.

#1 James McCudden?
#2 FJ-1 Fury? -- I don't actually believe that, but ??
#7 AC-123?
#8 A Loach is an observation helicopter, typically OH-6 & OH-58, that was used in Vietnam as "bait" to reveal AAA and other ground threats, so that attack helicopters could make the kill. It was highly hazardous duty.

#7. I believe the AC-119 is the missing one.
#8. I don't recall the OH-58 being called anything but a Kiowa or just an OH-58. If it was called a Loach at was after the Vietnam war. The Hughes OH-6 was the original "Loach". It was called so because of its original designation; Light Observation Helicopter or El Oh Aitch. This was much like how the "Huey" name came from the original Bell HU-1 designation. The "Huey name didn't make much sense after they changed it to UH-1 in 1962 but by then the name had stuck.

..but African swallows are non-migratory.....
Since no one tackled #3.... A mechanism designed such that once armed (through various means), upon contact causes the iron bomb to go boom......

#1.I believe Billy Barker was the highest scoring Sopwith Camel ace in WWI. But he was flying the Snipe by the end of it. He got several kills in that type also.
#2. The first Westinghouse J-40 powered McDonnell F3H-1N "Demons" were so unreliable that after losing six aircraft and four pilots in rapid succession, all of that series were permanently grounded. Later versions had the Allison J-71 engine and were considerably more successful.
#3. A plain vanilla "dumb" bomb usually can have both nose and tail fuzes. Both fuzes have a propeller or windmill that is prevented from turning by a piece of wire attached to the aircraft and threaded through the shaft of the "windmill". Before dropping, the pilot selects either nose (instantaneous detonation on impact) or tail (delayed detonation, can be as little as .05 secs or as much as 10 secs or more). Once dropped, the appropriate wire attached to the aircraft pulls free from the windmill and once a given number of turns are completed, the bomb is armed and the fuse will detonate it upon impact or after the specified delay if tail fuzing was selected.
#4. The Fokker E-3 Eindecker (Monoplane) has a single row Oberursel rotary engine and one Spandau 7.9 mm machine gun synchronized to fire through the propeller, the first practical application of gun/propeller synchronization. Upon its introduction the British press referred to it as the "Fokker Scourge" due to its initial successes and the apparent inability of the allies to come up with an effective counter for it. The Fokker E-IV was supposed to be the improved version, being fitted with a more powerful two-row Oberursel rotary and two Spandaus but more isn't always better and the lack of reliability of the engine resulted in only 49 of the "improved" Fokkers being built.

#1 is still up for grabs.
Patrick got #8 first, Dave filled in the details. Loach was the generic name given to the scout type helicopters such as the OH-6 (which was called the Cayuse, BTW) and the OH-58. A Vietnam vet friend of mine told me once that the easiest way to identify a particularly nasty target was to look for the burning Loaches...
Dave got #'s 2, 3 and 4.
Still looking for #5 also.
Wayne, I never mentioned migration, it might just be a local IFR flight.....
;D

#5. An angle of attack vane on a Boeing is a sensor vane, usually on the left side of the forward fuselage, that streamlines itself with the relative wind and provides a reference angle to the stall warning system that lets it know when the airfoil of the wing is approaching its critical angle of attack. It is usually referred to as a stall vane and can even be a dual system with two vanes and two separate systems. (UAL's later 727s were all dual vane equipped.)
The stall warning computer that it feeds into is also programmed to take into account flap setting and other relevant parameters. It is usually hooked up to a stick shaker system that lets all but the densest of airplane drivers know that the aircraft is about to go into sudden look down mode.
Some aircraft manufacturers take into account the fact that a stick shaker is not enough for the denser pilots and so a stick pusher is also incorporated into the stall warning/AOA system.
Some AOA vanes, like those on military aircraft and in certain Learjets, are hooked up to a gauge on the panel that shows a red/yellow/green indication of how close to critical AOA the airplane's wing is getting. Some navy AOA systems, the one in the F-18 is the one I am thinking of, have a red/yellow/green vertical display that is one of the more important fast/slow instruments during a carrier landing.
Some AOA sensors are not a vane at all but are a probe that sticks out of the side of the aircraft's nose. The probe has slits along its axis that sense the direction the relative wind is coming from very accurately and send the data to the same kind of stall warning system as previously described.
I have always wished that all large civilian aircraft were required to be equipped with an AOA gauge in addition to the stall warning system. Wind shear recovery is only one of the things that it would help with immensely.

Galvin filled in the blanks on the AOA vane.
Still looking for #1. Hint--Canada.

William Avery "Billy" Bishop (Later Air Marshall Bishop)was Canada's highest scoring ace with 72 kills but he also flew SE5As.

..ruled that one out. There is no records anywhere of a swallow of any type being certified for IFR flight. Given that we know that the empty weight of a swallow is 6 ounces, and we know it would be over gross carrying a 1 lb coconut, the gross weight of the swallow would have to be less than 22 ounces. Add in the fact that swallows (of all varieties) are known to be in wide scale production, one must conclude that they are certified under the Special Light Sport Aircraft (S-LSA) category...the only category which this airframe qualifies for ceritification. Therefore, the swallow must be operated in accordance with the operating limitations given the aircraft at the time it receives its airworthiness certification. Therefore (sorry to be so longwinded about this.....) the maximum speed in level flight with maximum continuous power is (Vh)-138 mph or 120 knots!! Ta DAAAaaaaaaaaaaaaaaaa !  |

Ah, Wayne, you are entirely correct, but if the swallow was registered in the Experimental category and had modifications not contained in the type certificate, then the airspeed velocity would certainly be different. Given the differences in the regulatory climate between Africa and the rest of the world, such modifications are not only possible, but probable......I will ask Uncle Sancho. He'll know for sure.
As for question #1--hint #2..he shares surname with a famous race car driver.

Donald Rodererick McLaren, 48 aircraft and 6 balloon kills.
(Bruce McLaren, was a noted race car builder as well as a driver. He was killed in 1970 testing a new design at Goodwood in England.)
