Thumbs up Oleo struts. I don't need no stinking oleo struts.

As a start,The F-104 did not have conventional oleo-pneumatic shock struts. The landing gear on the 104 used struts that were filled with a viscous fluid that would compress under high landing loads. The compression of the fluid would absorb the landing loads and the fluid would then decompress but it would not overshoot like a conventional landing gear. Once the aircraft hit the deck it would stick.

A similar shock strut was used on the tail landing gear of the Sikorsky S-56 (H-37).

If you really want to get into an argument try this. Conventional hydraulic fluid (red) will under a specific load compress to 58% of its static volume.

I may have twisted the above figures a bit.

The volume loss is 12-18% at 42,000 pounds pressure.
