If there is one thing that flying in Planetside 2 makes me do on a continuous basis, its lament the half-plane half-helicopter light aircraft in that game. In my experience, they're usable, but don't really excel at either role, and their stupidly low speed makes them childishly easy to kill.

I know everyone loves to talk about reality being bad for gameplay, but we have attack helicopters and fighter aircraft as separate entities for a reason. You really can't make one aircraft that performs both roles adequately. Hell, the X-50 program tanked, and that was only aimed at making a helicopter that could fly farther and faster.

I would highly recommend that these two types of aircraft not be combined, and that we have a unique and capable asset for each of the roles they would fill. Additionally, could we get a more responsive version of the Precursor Dropship flight mechanic for Gunships? Pulling loops in Dropships was silly, but fun, and some of my favorite memories of BF2142 were of gunning for the Gunships in that game with how maneuverable they were.

There are so many vehicles we haven't seen yet. Fighter jets are just one of them, bombers are another.
Consider the "icon map" on the help screens. It distinguishes between light, medium and heavy vehicles, ground and aerial. So far we have only seen the light aerial vehicles (empty triangle icon), and on the ground we've only seen lights (empty diamond shape) and heavy (full diamond shape).

Dropships in this classification, are flying LAV's.

would be nice if the fighters was EVE players coming down in destroyers... that would be awsome.

The smallest ships in EVE, frigates, are about the size of the MCC. There are drones that could only be about the size of an LAV, but there's no reason to believe they're atmosphere capable.

Now, we probably won't see jet aircraft like we know them today. Reason being DUST aircraft are designed to work on any planet, including ones with little or no atmosphere. Fixed wing aircraft need atmosphere to generate lift, but vector thrust aircraft like DUST's dropships do not. So even our gunships, bombers and, (though I can't imagine them actually being implemented) fighters will probably use the same flight physics as the dropship.

You can actually see a gunship briefly in this video. One flies by at around :49 and another flies around the corner at :51 and blows up a HAV.

Destroyers are over 200 meters long...

If not longer :)

The MCC is about 200m in length if I recall. In EVE that is small

The smallest frigates, basically the Amarr are about 70-80m long. The large frigates are Caldari and Minmattar, those are around 100m long, and the minmatar around 130m on the Rifter if I remember. Destroyers are between 223m and 288m long for the current lot of em. Cruisers are anywhere from 220m to 560ish meters. Battle cruisers tend to be around the same lengths as a lot of cruisers but much more massive in size.

And food for thought. That Ferox that passes in the foreground at the beginning of the video is 505m Long. So that gives you some perspective as to how large the war barge is going to be. My guess is pretty close to the size of a mother ship, or close to the size of a titan. Since Titans are up to about 18km long well, you get the picture.
