Requests: On the need of finding something of use

Inspiring Submarine designs with a lot of Steampunk

We need more fancy rides, so I seeked for 3D Meshes for futher implementation into some Simulators and what I had to find was that most things don't even exist in the virtual world. While researching I found out my preferences are somehow unseen or let's say if you ask me, I would reflect a very specific nerd-faction. This means I'll take my opinion and I'm asking in the name of all vehicle related sim players that want to be early adopters, too. Here is some opinion leading for all of us. I hope you agree with me in particular. This list is aimed to bored Modders in search of something special. Thanks in advance!

These are some of the 3D-Meshes or Mods me and others would love to see:

Marine
U-Boat Type XXI (kewl design, hot historical specs)
U-Boat Taifun Class (huge and modern)
Seabreacher X Shark, Dolphin or Orca (fun and innovative)
Sailing Boat Dehler Dehlya 25 (tiny and cute)
Deepflight Black Hawk or Deepflight I or Challenger or Super Falcon Mk II

...

Air
The Jet from the movie G.I. Joe 1 (the non AI two-seater variant)
Synergy Aircraft (a crowd funded futuristic plane)
Mi-24 (a russian helicopter)
He Triebflügel (epic WWII concept aircraft)
He 112 (good looking, good manuevering)
Some Horten Glider Planes (one-wing concepts, needs flight skills)
Wingsuits (YAY, needed)
...

Space
Mars Attacks Flying Saucer (kewl design, epic gadget)
The Flight of the Navigator (unique design, for fantasy purposes)
BSG Rising Star (one of the most beautiful ship designs ever)
A super movable Spacesuit (needed for some)
...

Terrain
Some more very freaky Concept Cars (from real manufacturers).
Some hotter Mech Warrios (more sleek, please).
More different Byclicles or how about some virtual Inline-Skating?
...

Notes
All should have cockpits, except the two last ones. Thanks for developing! Ah and thanks for creating any awesome vehicle design that not got mentioned in here. Keep up the good work! :)

This topic is sheduled to be filled from time to time with whatever I end-up researching while looking for hot mobiles. Soon with pictures and more fancy entries.
