The Australian report is rather interesting, given that the RAAF ultimately decided against using the Chipmunk to replace their Tiger Moths, instead opting for the home grown CAC CA-25 Winjeel. The Winjeel had its own spin problem, it was particularly difficult to make it spin! CAC modified the design by shifting the tail fin forward along the fuselage by approx. 400mm, reducing the stability of the aircraft and enabling the students to actually put the thing into a spin.

Worked B727s for Airlift International in Japan while in the US Air Force and Eastern QC B727s while working for Flying Tigers later. Loved the airplane.

Andras, thank you for sharing this experience. N136FE was the 727 FedEx donated to my aircraft mechanic school, and I have marveled at the type ever since I started its No 1 engine. I greatly appreciate the insights you have offered into its engineering.

I’ve been searching for videos like this, ones that really dive into the engineering and design choices behind aircraft and their relevance

Great video. Thank you for the video uploader.. ❤

Will you do a video on other aircraft like the 707?

I love and miss the 727. This two part series was wonderful. Your commentary is outstanding.

Why would anyone do a 'deep dive' on an obsolete airframe.

1985 my first AEF at Manston, we flew over the white cliffs of Dover - I was bitten by the beauty of flying at age 15!

Nice docu. Thanks!

Thanks for the motivation to finally get python set up on my laptop! Worked as advertised once I figured out how to get all the modules, e.g. metar module, set up!

Another great vid and must have been an awesome ride along! Gee, surprised to see the flight engineer reaching between the two pilots at critical flight stages.

Great video, one of the best I have seen on youtube. Thanks.

Really well done! Worth the time watching every minute! Great book shelf!

Whatever course it is you’re running at Southampton, I want to enroll.

Absolutely brilliant video. Thank you, loved every second of it

26:25 is that from Ron Rogers?

Love the aircraft. I flew the 200 all pax, all cargo, and the only -200 combi. The long body, wings, and tail are beautiful. One doesn't even hear the engines when you start up. When thrust is added for takeoff, there is only the increased sound of air conditioning airflow(and the altimeter vibrator clicking away). Same on the climbout with peace and quite....until 250 knots, then it gets loud as the airflow noise gets louder and louder. Landings could be interesting. Go for a while with a streak of decent ones and then the inevitable firm one. Sometimes one would be expecting a firm one and would get a greaser. Many would say that you flare by pulling back on the control column and then push to roll it on, but it was really just a relaxation of the control column. Remember, the nosewheel brakes don't necessarily get activated. They only operate when the brake pedals have been deflected beyond a certain amount(something like 50%) so that they are not being used unless they are really needed. I saw a flaps 28 position in the cockpit shot. That means a Raisbeck noise mod which intentionally reduced max flaps deflection to reduce required thrust on approach.

46:53 There was a DB Cooper copy cat who did the same thing. Many people say DB is Flyod Mcoy. So twice the air stairs were used to parachute out with cash.

I thought they pinned out flaps 40 as a cheapo hushkit.

So basically the same job as a firebomber.

Absolutely amazing video! Loved it! Thank you for making it!

150FT how good, I flew the P-8a here and lowest we were restricted to was 200FT over water which feels epic in a 45 degree bank turn!

I first flew on a 707 when I was too you to remember I was well, 13 months old to NY. But I remember very well my transatlantic flights when we flew back to Europe when I was 4, 5, 10, 12, 19, and then many interprovincial flights in Canada. It turned me into an airplane geek. I remember very well the older planes, we landed in Iceland, that was not fun, I was 5, and the plane kept going back into the hangar. My Mother is a nervous flyer, as evidenced by her nails digging into my arm HA! I flew the old Constellations, 707's, lots of 727's and 737's between countries in Europe in the'70's. In Canada there were many DC-9's, then on to the 747's to Madrid, and then another 727 to Tenerife. My favorite of all of them though was the 757, that thing blew my mind...the power!!! Last one was a 767, till a boring Dash 8 to New Brunswick. I miss the older planes.

The Mighty 727! The first Passenger Jet I ever flew on & had the privilige of being at the controls of (I was 10, I wasn't in control) I did get to Turn & Bank though. My first flight experience was in a Glider, I was 7 back then (Yes I was allowed to have the controls after take off) Different times. How the world has changed. I'm not even 50 yet.

Fascinated to finally finds someone who also goes by OEW normalised comparisons, I got drawn to it trying to decipher what went wrong with the A340, everyone blames the 4 engines, but nobody bats an eye at the absurd weight of the 345/346...

Amazing video! Ive always wondered about the viability of ISA globally. Geopotential height is always a metric i struggle to wrap my head around. The thing i always try to remember is that a low geopotential height means the atmosphere is less dense there, so you have to go down “deeper” into it to achieve the same pressure as compared to a dense region. As usual with meteorology, knowing what something means is a lot different than knowing why it means it.

My Father flew this bird for about 30 years, at TWA, and then at Fedex. I know for sure he flew these beautiful birds that are still serving faithfully. What an airplane!

Boeing should can the 737 design and bring this back with two tail engines

One of my favorite planes to fly in X-Plane is the 727-200 Advanced. I use the CIVA INS instead of the FMS. Very hands on to fly since it was made for 3 and I’m the only one flying on my PC flight Simulator. Also the 727 didn’t have Auto throttle which keeps you quite busy.

It would be cool if X-Plane flight Simulator had this mission plane as we already have a really nice 727-100, 200 Adv. & Freight versions by FlyJSim.

I am not a pilot but a stall can be the Most dangerous stage in flight if Not recovered by the pilot the engines start losing power this Applys to the B727 .

How would the pilot recover from a stall At 150 feet over the sea without ditching into it ???

18:29 as if he’s running skydeamon

designed in the 50s.

Cusco Peru's airport at 11,500 feet asl, was no problem for the awesome, beautiful, sexy Boeing 727. Excellent video!

Excellent documentary and educational. Thank you for researching and creating this. 🤗

See Dan Gryder for DB Cooper story.

I wish I had seen this video before I did flight test work on the 727. I heard that the deep stall with Wallik (sp?) as caused by the FAA pilot flying saying, "I wonder how it will handle if we stall it with the spoilers open". We had a lot of fun flying all over the envelope. We flew as fast as anyone, except that one TWA (?) flight that went supersonic. We did aft cg stalls, but with the flaps up. Pitch stability was neutral at the highest speed. That wouldn't pass today, but the Boeing and FAA pilots thought it was acceptable, I was told. Boeing gave us guidance on sizing fences that we put on the FedEx hushkitted engine pylons to create vortexes land at the horizontal stabilizer high angle of attack to prevent deep stall.

Used to see them regularly at Doncaster.. I asked if I could get up close but they wouldn't let me :( .. Unfortunately, Doncaster has since closed down and I havn't seen them since.. Only place closest to me where I think they still go to is Teesside.

What an awesome set of videos! Love the detail, meticulously layered in without sounding too distracting. Really enjoyed these 727 videos!

Your video is COOL!!! You say 60 years old, is the Boeing 727, and I'm age: 61, and to boot, I'm The New Year's Baby of 1963!!!

Back in 1987, I worked with an MX crew in Fort Lauderdale that performed a 'B' check on a B727 owned by Pia Zadora (N888VT) - The exterior paint job was like that of a Zebra. The interior was done up like something out of The Arabian Nights.

I always knew the B727 was a incredible plan with a huge service record, but I never knew that it was this redundant. Look at the MAX program today they went 180 on their own felosophy

This is a wonderful video, well done for Part 2! 13:38 wasn't expecting to see a Qantas B767 and a Dan Air B727 in Cairns in this video, what was the Dan Air B727 doing in Cairns? was that during the 89-90' pilots dispute? A question about the role of Flight Engineers back in the old days, what would happen if the F/E became incapacitated? would either Captain or First Officer know how to manage the systems in the event of a F/E incapacitation?

Awesome vid!

I’d just sell it to the kid in the first place

Hi! Just a slight correction. At 11:42 as you mention the bugged speed. There are two white bugs before the orange IAS-bug. First is at about 118 knots and the second at about 128-129 knots. At 12:02 you said "the white bug at 80 knots", but between the start of the scale (60 knots) and the first bug, there is no bug set at 80 knots. I would therefore assume, as this is a Class A jet being operated under EASA-NCC CS25 (I will assume), the V-speeds bug settings are common throughout for Class A CS25-equipment, meaning that the first white bug is V1 (in this case about 118 knots) and the second one is Vr (at about 129 knots). I don't fly the 727, but with about 1700 meter TODA and 74ish metric tonnes TOM, a V1 at 118 knots, flaps 20 and engine power at (probably) TOGA-setting sounds reasonable, as compared to 737-performance data. Super fun to watch and thanks for creating this content! Sincerely EASA commercial pilot.

From what I was told a 727 is quite the hot rod of airliners, very fast but not very economical or quiet. I rode on many and thought that as long as you were towards the front of the plane they were very quiet and comfortable
