When could we see this site?

Hopefully someone will come along and offer to create the site (IMADB).

I'd make a better lurker than a spotter, but it would still be a lot of fun!

Just a question, why are you all taking this so serious and deciding where to put each vehicles if noone seems to be willing to run such site?

Yes. Let's just keep it focused and stick to anything that actually flies and it is controllable and which a person can ride inside, planes (including rocket planes), helicopters, gliders, airships and autogyros/gyrocopters/microlights (there won't be too many of these in films). Hot air ballons I'm not sure about because the ballon part can be any kind of shape and underneath is just a basket with a hot air torch, how would we assign makes and types to these? And I don't think we should bother listing hanggliders, put them in comments. Maybe we could list them in comments.

And no Starship Enterprises or Millenium Falcons

That's rather for a site about weapons/arms, no?

About Aircraft, airships would be fine and I guess hot air baloons would be OK (don't know who actually makes them though), but I'm not totally sure about rockets because they are not reusable by nature. The Moon rockets (from films like Apollo 13)... maybe, but I don't know about missles. Missles aren't actually transport (yes, they transport bombs to targets, but not HUMAN transport). When in a film a fighter plane fires a missle, are we going to list that?

That's what I think as well

Personnally, as IMCDB , IGCDB does already exist, I would find much more logic to create separately:

IMADB (Aircraft meaning = all types of flying machines. Balloons (powered or not), gliders, airplanes, helicopters and space rockets, the case of weapons rockets is specific and I don't know if it should have its place ?)

IMTDB (Locomotives , anykind of them + wagons)

IMSDB or IMBDB (Ships or Boats)

Just to make things clear, how many modes of transport would IMVDB list? Aircraft (planes and helicopters and maybe gliders), Trains, boats/ships, everything already listed on IMCDB (cars, trucks, buses, motorcycles, tanks, golf carts, ground conveyors, construction vehicles). Anything else? Are you really serious about listing horse-drawn carts/carriages and chariots? Are you a fan of these things?
