I'm sure the only reason ATS bothers to keep him around is that everyone enjoys a clown.
I think I'm going to go ahead and file Ultima under "crackpot troll" and treat him accordingly, as I advise others to do the same.

Incidentally, I would encourage you to stop the personal attacks against me.

So why do you then type the following comment, where you launch another personal attack against a fellow member?

Lets look at the steel in the F-4.
1. Keel and rear sections.
2. Tail section.
3. Tail hook assembly.
4. Landing gear and wheel wells.
5. Engine bays
6. Engines.

Just keep proving my point about the believers.

* The Phantom was made mostly of aviation aluminum alloys, but about 10% of the aircraft was built of titanium, a new metals technology at the time. There were seven major aircraft subassemblies, including forward, center, and aft fuselage assemblies; a wing center section; wing outer panels; and the tail assembly. There were initially six fuel cells in the aircraft, four in the fuselage and one in each wing. Flight controls were operated by a triple-redundant hydraulic system.

STRUCTURE:
Centre-section and centre wings form one-piece structure from wing fold to wing fold. Portion that passes through fuselage comprises a torsion box between the front and main spars (at 15 per cent and 40 per cent chord) and is sealed to form two integral fuel tanks. Spars are machined from large forgings. Centre wings also have forged rear spar. Centreline rib, wing-fold ribs, two intermediate ribs forward of main spar and two aft of main spar are also made from forgings. Wing skins machined from aluminium panels 0.635 m (2[1/2] in) thick, with integral stiffening. The fuselage is an all-metal semi-monocoque structure. Forward fuselage built in port and starboard halves, so that most internal wiring and finishing can be done before assembly. Keel and rear sections make use of steel and titanium. Double-wall construction under fuel tanks and for lower section of rear fuselage, with ram-air cooling. The tail unit is a cantilever all-metal structure, with 23º of anhedral on one-piece all-moving tailplane which has slotted leading-edges. Ribs and stringers of tailplane are of steel, skin titanium and trailing-edge of steel honeycomb.
The J79 required alot of extra steel around the unit in order to protect the area surrounding the engine from excessive heat.
Just under 1,300 pounds of heat shielding went into the F-4 just because of the J79's heat emitting characteristics.

Well your site is just missing the steel that other sites show, you jsut need to do better research.
This site shows 7.7 to 8.5 % titanium, with enginse added puts
it up to at least 10% or higher.

In 1930, Jack Northrop introduced the use of riveted aluminum for the semi-monocoque flush-riveted aluminum fuselage and aluminum stiffened skin riveted to flanged shear web wing box structure of the Alpha aircraft. ...This type of structure was also utilized for the Northrop Delta and Gamma aircraft and employed by Douglas for the DC-1, DC-2 & DC-3, with the upper cover stiffened by riveted corrugated aluminum sheet. With the success of the DC-3 in 1936, riveted aluminum stiffened skin stringer/frame structure became entrenched as the preferred concept.

Personally, I'd like more specifics to definitively prove that it was all steel. That sentence isn't conclusive enough to point to all steel.

Please don't misquote me, i never stated it was all steel, just mostly steel.
When you add all the components and the engines together you should see that there is a large amount of steel in the F-4.

Guys, please remind me what this has to do with the 9/11 discussion? Thanks, I was just wondering if we were starting to drift off topic a bit.

It was because of people trying to compare the video of the F-4 hitting the steel reinforced power plant wall to the 757 hitting the wall of the Pentagon.
We know the 757 is almost all aluminum and the F-4 has a large amount of steel (including the engines) so the comparision is not a very good one.
An aluminum airframe is not going to penatrate through all the walls and collumns of the Pentagon.
