Great video. This is yet more proof of wasted potential in the Bf 109G as well, given that if War Thunder is at all accurate, the G-2 model could, at 1.42 ata, achieve 563 km/h at sea level and 696 km/h at 6700m altitude (this can be extrapolated to ~700 km/h at 7000m altitude). Furthermore, the Bf 109G was originally intended to have small clamshell doors (similar to those on the K-4) covering the front wheel wells while in flight (hence the squared-off outer edges of the wheel wells). According to some calculation that I found, a Bf 109G-2 with these could realistically achieve ~570 km/h at sea level and a whopping 730 km/h at 7650m!!! I was honestly startled when I found these numbers, because I always thought the Bf 109 was supposed to be slower than the P-51 by a lot. Turns out that while it was somewhat slower, perceptions of the Bf 109's performance potential are also often shaped by many databases using tests of damaged aircraft with derated engines (I was also similarly surprised when I discovered the Ki-61-II could theoretically go 681 km/h at 8530m, or the J2M3 Raiden cold theoretically go 671 km/h at 4980m--when previously I thought both aircraft would be limited to about 600-620 km/h). Then again, when looking at performance figures it is important to understand the context that they were recorded in, and many of the more "unflattering" tests of the Bf 109 used aircraft that were in rather rough condition or relied on derated engines (or had added equipment left unaccounted for--the often-quoted 621 km/h figure for the Bf 109G-6 comes from a British test of a gunpod-equipped night fighter variant limited to 1.3 ata). To get around this issue, I rely on a mix of data sources, and in the case of the Bf 109G use Finnish data quite a lot given that the Finnish Air Force used the Bf 109G until 1954 (and according to their manuals, a Bf 109G-6 with a fixed tailwheel can go ~540 km/h at sea level and ~650 km/h at 5000m, extrapolating to a rated altitude of 6700-7000m we would get a top speed of 670-680 km/h at 1.42 ata, which seems to be in agreement with a maximum cruising speed of 590 km/h at 6300m and a top speed of 635-640 km/h at 1.3 ata--as well as with my estimates of the performance potential of a G-2 with a semi-retractable tailwheel (and potentially wheel well covers) at 1.42 ata).

Interesting, I've never heard of reclaiming exhaust energy and putting it straight into the crankshaft. I have thought in the past that there has to be something on cars that could be run off the exhaust other than a seldom used turbocharger. Thanks for sharing.

I’ve always wanted to fly a B727, I just think they are beautiful airplanes. I was fortunate to jumpseat on several 727s in the late 90s and early 2000s. I’ll always remember those new hire pilots sitting as busy Flight Engineers. Enjoyed this video immensely.

I wonder why they could still call it a P-51 Mustang if it was a completely new design?

0:51 Sorry to tell you that Scania uses turbo compound on their I6 13L diesel engine

Just discovered your channel today and OMG it's awesome! I'm a huge WWII fan so your videos on WWII fighters have been very interesting! You are amazing at explaining things clearly and concisely!

The 262 had and electrically heated windscreen.

I also saw a german TV show here on YT with a DC-6B of Red Bull with some special propellers flying very efficiently.

I'd imagine Boeing would be hit with an anti-trust lawsuit, courtesy of Airbus, if they tried to make a regional airliner

I laugh at certain people criticizing Brazilians for defending their point of view, did they want us to follow the Smithsonian guide? The brothers may have advanced faster in developing control surfaces, but without a shadow of a doubt Dumont put a heavier-than-air machine to flight first, taking off and landing by its own means... Even Boeing knows the quality of Brazilian engineers, but the 'experts' here are ironic and call the 14bis a crate kite... ok. We never belittle something well done, but excessive marketing doesn't work in aviation, accident victims know this well. We are proud of our aeronautical ingenuity, our Embraers are among the best in the world, equally, there is no need to waste a lot of saliva to convince a bunch of moronic nationalists about the obvious.

Hi. Thanks for including a picture of N727US. Unfortunately, it's been repainted. The red, white, and blue was a much more beautiful image.

I had a solenoid unbeknownst to me slow drip into my intercooler which and then ended up shooting enough liquid into the head to separate it from the block. I'm so pissed that the solenoid cost me an engine. I will never trust those things again

I heard that Hawker Siddeley were in discussion with Boeing about a joint programme on the Trident. Boeing were invited to Hatfield and were given all the info on the Trident. Boeing then went home, with the info then told HS that they werent interested in the concept and collaboration. Next thing ta da the 727 appeared.

The elephant in the room is the tactic used by the escort fighters.. Did they fly level at a similar altitude as the B 17 bombers - or did they fly top cover high enough above the bomber in order to perform high speed dives onto the German fighters as the Luftwaffe flew up to attack the bombers.. The reason why Doolittle ordered escorting fighters to fly ABOVE the bombers so they would superior speed to use in their fight with the German fighters.. Doolittle did this because he had consulted the British General Dowding about how the British had won the battle of Britain because the german fighters were required to stay near the german bobmbers.. But- when the fighters stayed near their bombers they lost their advantages in speed because they could not dive down on the opposing fighters.. After a few battles using the stay near the bombers tactics the attacking fighters having taken much higher losses would cease to be a credible threat to the bombers.. best Bruce Peek

So the anti side is merely adopting the career covering lies of the militaries higher brass.. We know from the history of the Vietnam war, the Korean war, Reaguns assinine military disasters in Lebanon, and central america, the second Iraq war, the fights against Isis and on and on- that the American high brass routinely made up lies as their first justification whenever they got caught in a lie which was most of the time. best Bruce Peek

Thank you Greg for this video. Decades ago, I read about Gustav Whitehead's powered aircraft. Your analysis of the power to weight specs compared to today's engines alone quells any notion in my mind to the validity of his claims. I didn't know that the famous newspaper article was a letter to the editor. Well done, Sir, for putting issue to bed for me. Thank you for all of your well researched videos.

Blowing an engine will result in less performance.

Having watched Greg’s video: ruclips.net/video/aCLa078v69k/видео.html that was the starting point of this debate about 52 min 10 s into that video, this is what I hear: “The Bomber mafia were so convinced in their belief that bombers did not need escorts that they derailed attempts to add drop tanks” “Clung to these beliefs during 1942 and most of 1943” “Even trying to use other bombers as bomber protection rather than supply drop tanks” But what I don’t get here is if the USAAF leadership truly believed that escorts were not needed, then why are the B-17 raids over the European continent done in 1942 and 1943 that were within the range of the escorts (with no drop tanks) escorted by Spitfires and P-47s? If the “Bomber Maffia” were so convinced that escorts were not needed, then why use escorts in these shorter range missions but then suddenly decide that they were not needed for longer range missions when drop tank were needed? Isn’t that rather odd? Because the B-17’s were escorted in 1942 and 1943 when the fighters had the range without drop tanks but then they were not when the range is larger and drop tanks would be needed. So if it was really feasible to add the 200 gallon drop tank to the P-47s for the Schweinfurt raid and they did not do it, this begs the question of why they were using P-47s to escort without drop tanks earlier on when the bombers mission was within range? This point seems rather contradictory to me and rather like a strong point for Bill’s argument that the P-47 simply could not carry a suitable drop tank at the time.

Liked to fly the George in microsoft combat.

To me it's a tie between the bearcat and the seafury

John Wayne was never in the service! He played an aviator. His rival Jimmy Stewart was in the service and was an aviator!

Greg I love your channel, please keep it up. I finally got to listen to your “debate” on P-47 range and would like to pass in a few quick thoughts. First…some of the P-38 story in the ETO supports your argument on the Bomber Mafia’s lack of effort on the P-47 range. Yes, the P-38 certainly had issues, more so in the ETO than elsewhere. However, much could have been done if leadership decided to make addressing the problems a priority and “kicked some ass”. The cockpit heating/defrosting is one example and the dive flaps (passively shrugging shoulder and not demanding immediate replacement shipment) is another. Second…while hardware was one issue that betrayed lack of focus “mindware” (fighter tactics) was another. Even when escorts started becoming available Eaker refused to change tactics that’s one of the reasons he got fired. I’m a long time bomber guy. You got the mindset exactly right. Ideologues have a hard time shedding long held beliefs, even in the face of (unpleasant) evidence. Keep it up, God Bless Marc J Dinerstein, COL, USAF (ret)

Type 92 model 3. Best torpedo in the war.

CLEARLY: You won the debate Greg. ----PLEASE do that additional 30 minutes on the multitudes of the tanks themselves, pressurization, racks mounts, etc. and the ultimate affect on range in greater detail. Your point in concise terms and time: 1943, 200 Gal drop tanks on P47 C's would have (not simply "could'a") reached Schweinfurt and back in an escort role. Period. The quantification of human behavior (my field of study at the Masters level) is less verbatim than say rates of fuels consumption at given engine setting, head/tail/cross winds, altitude, temperature and other relatively easily quantifiable metrics are a snap compared to basic attempts at understanding human behavior. I fully concur, the "Bomber Brass" (I'll wager Mr. Marshall found your use of the well known expression "Bomber Mafia" offensive, but as one familiar with human nature, I'd seriously doubt he'd admit it.) were the impediment here with as you've stated a CYA approach to the subject. There are far too many examples in other war-decision contexts to say "no" to your base conclusion as Mr. Marshall has. And yes, I too do prefer the P47 to the P51 as it isn't only and "all about looks" here (or with cars as you also know) as the masses do indeed tend to be obsessed by appearance alone.

I wonder if you have read this book Greg? I think it will change your mind. Scapegoat: A Flight Crew's Journey from Heroes to Villains to Redemption

F4U all day

According to Wikipedia , the Packard Merlin used in the P-51 that fought the Luftwaffe was rated at 1380 H.P. That seems like a low number considering the SeaFire had a 1550 RR Merlin. Was the Packard Merlin of lower HP than RR Merlins? Was this why Luftwaffe could out climb P-51 D.

Dry weight of Ash-82FN typically used on fighters was around 870kg. In your comparison you are using 1020kg dry weight which was standard for Ash-82T used on late soviet piston engines transport aircraft like IL-14.

please do a video on the brewster buffalo. i dont think it deserves it's bad reputation. i've done research on the airplane regarding the pacific. The Buffalo was flown by bad pilots(green pilots), poor Logisitics, and bad tactics plays more a role IMHO. Nobody in 1941 really took the Japanese air arm seriously. Any airforce put up by Japan was seen as nothing to be concerned about.

Felton has good content, but his specialty is *_not_* aircraft.

There is still a Leslie Groves Park in Richland Washington, a city that was grown for The Manhattan Project.

Enjoyed the follow up Greg and would watch if you do more sir. Agree on skip the not relevant comments. Maybe just make a global comment at the beginning and end acknowledging and thinking everybody for them. A scholar and a gentleman sir.

Greg, if you happen to see this, I did a follow on video to this video on my channel and tonight's livestream will be talking about the stuff we often leave off of our kit models including drop tanks which will no doubt lead to talking about your debate with Bill. Take care. Max

Thanks for the engagement and dedication to your audience, Greg. Youre truly a class act.

Hey! Subaru isn't the most boring car company in the world.. they have the WRX which is pretty damn fun to drive.

This is a great follow up video and i enjoyed it

The 727 is the plane that DB Cooper parachuted out of. The stairs below the plane in the back were lowered and he bailed out.

24:40 That I thoroughly don't understand. How can a tiny trim-tab push the rudder one way when the weight and aero of the entire plane are pushing it the other way?

This is the best 2 hoirs I have spent on youtube in years! Thank you all 3 of you for putting this together, and I would love to see more stuff like this in the future

Greg, thank you for elaborating on the lancaster's shortcomings in this regard. One question slightly off-topic that I have heard many times but don't know the answer to: Bockscar, the B-29 assigned to the Nagasaki raid, has Nagasaki painted on its nose art, but Nagasaki was a secondary target, chosen in-flight by the plane's commander, was it not? Am I just blowing smoke here? Was the nose art altered after the raid? I have heard (and my source may be dubious here, as I do not know its origin) that Bockscar was not the actual B-29 that dropped the bomb on Nagasaki.

Even with the technical difficulties, very well put together. I would lean to the military brass being at fault for both the original stance on drop tanks and also, the promoted known exaggerated bomber kill claims. IMO-The brass backed themselves into a corner and had to have a sparkling horse to save the day, and themselves.

There is no more pitiful schooling system than the brazilian one. I can tell you from experience.
