It is a T6 Harvard. They make a hell of a prop noise and I could never understand why it didn't have a bigger or 3 or 4 bladed one. The noise apparently is from the prop tips going through the speed of sound .

They had one as chase at A&AEE Boscombe Down for years and it used to drive my mother up the wall whith the noise! But they chose to live close to the airfield..

the Navy called them SNJs up until 1962. it IS a North American T-6 though. the Army Air Corp called them AT-6 and after the USAF became its own service they were just T-6.

in the States theyre known as Texans, the models exported to the British Commonwealth nations call them Harvards

Today is a historic day for Boeing. The last 747 rolled off the assembly line. After 50 years of production the famous jumbo jet will no longer be built.

Beautiful planes.

I wonder oif the drivers ever get confused as to what they are flying Dave?

Sting from the pop group Police had one and lived near my parents. they would see it quite often. My Mum used to go spare as she didn't like that prop and the tips when they went supersonic

A&AEE Boscombe Down used to use them to fly chase for the trials they were doing all the time. Dammed noisey things! But taught a LOAD of blokes how to fly!

I've wondered that too. My only guess is, because it was a trainer, maybe they wanted to limit the total airflow over the control surfaces so it wouldn't be too responsive, and would handle more like the larger and heavier planes the students would be flying once they went into active squadrons. Just a guess.

I was at a small air show in October and the announcer was saying that the USAAC chose the Boeing Stearman over the Waco UPF-7 as its primary trainer because the Waco was too easy to fly, having ailerons on both top and bottom wings. They didn't want to make it too easy on the student pilots.

You don't want a bigger (longer blades) propeller because more of the prop will be driven supersonic, making even more noise. Going to more blades would allow them to be shorter. The T-6 was a 1936 design, and it seems more blades were used in later aircraft designs. Some of the Spitfires at the end of the war had propellers that looked like a Nebraska windmill! I don't know when the first 3 or 4 bladed prop was used.

EDIT: I remember seeing bombers in a museum from WWI and some of them had 4 bladed propellers. The Boeing 299 (B-17) from 1935 had 3-bladed props. I'll modify my observation to larger planes seemed to have more than 2 bladed per propeller at that time.

Five-bladed Spit

Six blades

Griffon-powered six

Eight blades

Awesome!

Spitfire in Malaysia 1949/50, the bloke in the funny hat is my late father.

The Shacklebomber was a lovely aircraft to work on. The worst thing was the temperature in them at Changi was a bit warm though! They were the only infernal combustion engined aircraft I ever worked on. As an aircraft electrician the only real difference on them for me was the ignition system. Lots of plugs with lots of electric string going to them!

Yes, sad to see as the "Queen of the Skies" is my favorite commercial aircraft. I was at the Boeing Future of Flight Aviation Center a few months back, which has a view of the flight line of Boeing aircraft being prepared for delivery. I asked and one of the docents confirmed that the last handful of 74s were being finished up, all freighters. One of them was a Polar Air Cargo freighter and I could see it there brand-spanking new, across the field.

Fast-forward to a few weeks ago and I was watching LA Flights Live from LAX on Youtube, and in flies that very ship, delivered less than a month before! So at least we'll have years more of plane-spotting opportunities with these beautiful aircraft.

The Boeing aviation center sounds interesting, I need to visit some day. I'd also like to tour inside the cockpit of one of these new 747s. I'm sure the avionics are much different from the 747s I worked on when I was employed by Pan Am.

It's very interesting, and if you're visiting the PNW - it's about 30 miles north of Seattle - it's worthwhile. But unfortunately they've stopped doing the factory tour since COVID, and it's unclear when or if they will restart that. Years ago - when the 777 was a relatively new project, and the aviation center did not exist - I had done the factory tour and remember that as being really good.

This chunky high-flyer is a Quest Kodiak 100 3 utility aircraft, suitable for STOL operations from unimproved airfields. Privately owned. First time I've seen one of these flying over my neighborhood.

Great photo, hot and muggy over there, I'm sure. My father was in North Africa during the war. Mechanic in the US Army Airforce. We are working on getting his service records to see where he served. He died in 1985 at age 62 before my brother and I had a chance to ask him about his war time service.
