From another thread, wanted to get the Meteor thread back to its own...this should be the P-80 thread...here is what was there

The Meteor is a neat aircraft, and none are flying now. The big issue on Jets being fun/usable, is to answer the question "is there is a second seat". A historic plane. But outside the general interest of most.

Thread Creep

P-80's are rare, it is true, and none fly, the last one probably being a Chilean one in 1974. There are around 24 worldwide, and while that seems like a good number, only two are actually privately owned. That means they are the only two flyer candidates. Further most are outside and are in poor condition. When the USAF had the last 60 or so T-33 destroyed in Tucson in 2007, that went the last truly decent supply of wings and parts to support military restorations of T-33 or P-80 airframes. As far as civilian parts, the T-33 remains a parts plentiful aircraft with low demand.

But it begs the question, why not restore an 80' ?

Well its a tremendously historic plane, with the USAF putting the aircraft into the fight in Korea very early. and making the first USAF jet to jet kill for real when a Mig-15 fell to Russel J. Brown's guns. Five more Mig-15s lost everything to the P-80, but the swept wing Sabre was more of an equal, and handled the offensive air to air role. The USAF put the F-80C and RF-80 into service to help boots on the ground, and during 1951-53 the USAF at peak was losing the equivalent aircraft of one squadron per month to ground fire. One squadron of aircraft per month. m That is part of the rarity reason....Then as drones, and finally as export fighters. Also parts are similar to the T-33, so commonality led to consumption. The T-33 was far more valuable as a trainer in 1955 than the P-80 was as a fighter. Remember the T-33 was known as a TF-80C, so even the wing is a direct swap. All of them in service after about 1955 got "Fletcher" tanks, and so as parts were needed, the P-80's gave them up and faded away.....

To restore one would be wonderful, but the interest isn't there yet. The Stored and static P-80/F-80's with Korean combat history are unknown, and when in a decade or so it is discovered that a forlorn corroded P-80 is actually a Mig Killer or something of that sort...will she be savable? What are the P-80 mig killer serial numbers? The DFC mission aircraft ect...? Also it may be a good time to remind everyone that the T-33 was there too...and several were lost in combat in the transition/training role while dropping bombs. Historic stuff.

As far as modifying a T-33, why? It wont have the value of an 80' and it won't be an 80. Nobody on the net will ever let the owner forget it. Look at the beautiful Mustang and Spitfire restorations that are presented to the public to have some wag on the net post..."so how much is actually even original in that mustang or is it a replica...?" Tough to hear after 4.0 has been spent building your C model...And how many travel to see the Me-262 flying in Texas, or others? The jet "critical airshow mass" isn't here yet. Imagine the fun of building a real 80' after years of work to have someone yell from the ropes about how you "just cut up" some Trainer and its "not even a real jet...." (Why pilots aren't allowed to carry guns.)

A P-80 can be restored from a wreck, especially with a lot of T-33 donor help. I wish it was a matter of time, but the fact is that a T-33 is everything the P-80 is, without the history, and faster. Watch Greg Colyer's Acemaker on youtube, its an awesome jet and incidentally is the most popular warbird act in the country. Thats right, the most successful warbird act in the USA is a T-33. Would Acemaker be great in a Shooting Star? You Bet! But its a truth that a jet is a bit different than a piston bird...and its all gotta be built really strong. To build an 80 from a T-33 is not just removing a plug, but crating all new structure keels and longerons to hold that mighty thing together at many G's of force. The Acemaker display is very high energy, and if you realize the forces involved, an idea of a "simple" replica is nothing of the kind.

Its important to save the static 80's we have, and force the USAFM to bring them inside until we truly know what we have. Someday, perhaps. But for now support your local T-33!!!

There are a lot of "eh"s in that post.

"When the USAF had the last 60 or so T-33 destroyed in Tucson in 2007, that went the last truly decent supply of wings and parts to support military restorations of T-33 or P-80 airframes." Eh? As in, Canada, eh?

"As far as modifying a T-33, why? It wont have the value of an 80' and it won't be an 80. Nobody on the net will ever let the owner forget it." Eh?

"Watch Greg Colyer's Acemaker on youtube, its an awesome jet and incidentally is the most popular warbird act in the country. Thats right, the most successful warbird act in the USA is a T-33." Eh? Most successful by what criterion? Self-promotion?

Joe I lost you a bit in this above paragraph- while I agree that a P/F-80 conversion made from a T-33 would never have the same pedigree as a true F-80, and true rivet counters would always consider it a conversion, you seem to be saying that the T-33 that Acemaker uses is perfectly good for high energy displays, but a converted T-33 would not? I have heard elsewhere that the plug removal would be pretty straightforward- after all it was really the plug that turned the 80 into the 33....? Would be interested to hear why you think it needs major work with a new keel and longerons? Do major longerons/stringers run over multiple frames at that part of the fuselage- or are they frame to frame? I'm not sniping- just an honest question for my education. While it may be more than a plug removal, it looks doable. Thanks.

You can't just splice longerons and hope they'd be OK. I think I'm right in saying that on the T-33 the longerons run from the engine break right up to the front of the cockpit?

There's more to it than just taking out a plug and deleting the aft cockpit. Ultimately you'd have to ask why, when those with the bucks AND the F-80 airframe/s haven't taken the easier option.

I don't like the idea of mod'ing a T-33 into a f-80. The T-33 has a longer fuselage for one thing, and a dual cockpit arrangement. Even if you did, it still wouldn't seem pure. There are many T-33s out there to be saved. Effort should be made to make sure their future seems bright. People don't seem to worried about destroyed T-33s since there are many out there. But every year we lose more and more T-33's since towns and cities no longer want them displayed and cut them up. When will people start to say enough? When there are 20 left 10? If we got a warbird that is healthy in numbers, then lets keep it that way.

The T-33 has some of the most beautiful lines that bring a sense of nostalgia that you just can't get anywhere else.

:drink3:

Another 'eh?'. Unknown? Um no. Ditto for F-86s. Korean vets known and though some not very safe, they are known. Not listed in Wiki? Probably. But as I often say, everything is not on the (bloody) internet!

The NMUSAF says their F-80 is a Korean combat vet.

As for shows, just give a T-33 a cool paint scheme, that will be good enough for 99% of the audience. Heck, painting it up as a super hero's (Wonder Woman, Batman, etc.) would be good enough.

As far as a converted T-33 not having the value of a real F-80...come on, once you get out of WWII types, I don't think the "market" cares about rivet counting minutiae. Having the ONLY flying F -80 (even if it is a conversion) would add value. I would think it would be welcome at plenty USAF AFB open houses and Heritage Fight demos.

I think converting a T-33, would be a long shot, but twenty years ago I would never of dreamt I would see a FW 190 & a 262 in the air!!
So everything is possible.
Are there no P-80's anywhere, that would be salvageable, and offer a cheaper alternative??
I think this would be a cool scheme

Taken in 1948 of aircraft, assigned to the 94th Fighter Squadron, these were part of a group of thirty-one specially modified P-80Bs (of a total of 240 built) that featured canopy defrosting and used special greases and natural rubber for service in Alaska. The aircraft also carried high visibility orange markings for easier spotting from the air in case of a crash landing. Formed as the 94th Aero Squadron in August 1917, and known as the Hat In the Ring Gang, the 94th is the second oldest squadron in the US Air Force. Today, the 94th FS, based at JB Langley-Eustis, Virginia, flies the F-22 Raptor.

Forgot how friendly it was around here. As for the eh's....

There haven't been any US flown Meteors since 1993 at the latest. Not sure when N94749 last flew. I was not speaking worldwide as we were talking about the importation of a flyer. Interestingly, she will not be too easy to License I would think. I hope that's not true, but it is not a simple process. I have done it before.

The last great parts stock, yes, that's true too. The Canadian planes were surplussed and sold by 2002-2006. They were also all really great aircraft, CT-133 AUP birds. Not suitable for breaking for parts as they were "million dollar" rebuilds by Kelowna Flightcraft. They are awesome machines. The USAF ones were stored at DM, there were about 70 of them, mostly all 1958 serial airframes. Some were in really good shape, and even broken down, would have supplied parts and large sub assemblies for a century to the flying fleet. They were shredded in 2006 or 2007.

Acemaker is the most Airshows (number of shows) booked (scheduled) paid (pilot flown flight demonstration) Flying Demonstration (solo act) Warbird (fighter, bomber, trainer, military use 1940-1981 vintage).

Its more than a plug. Look at the structural repair manuals of both aircraft. While it is possible to splice a keel or a longeron, the simple "lego" "Tm" idea of removing a "plug" is not an accurate description of the structural modification to follow. A rebuilt spliced fuselage, spliced in every longeron ahead and behind the wing would be scary stuff for a pilot to contemplate. Jets apply huge forces to an airframe. Its not empty space, its all full of stuff, and so must be amazingly strong to carry flight loads...this is what it looks like when the keel is taken out!

Thanks for the informed reply Joe.
It certainly looks quite busy in there.
Changing the structure is not a simple process.

Don't be a stranger :wink:

Should anyone wish to tackle a project such as this and requires an F80 canopy, do not hesitate to contact me. Especially if you have a new surplus F7U-3 canopy to trade! ( hey, a guy can dream can't he?.....) :roll:
