Shadowrun is a good setting because it makes sense. And while this particular example may grate on my nerves cause I'm studying in the institute of aviation, I just don't think we should be handwaving everything for no reason but some bits of the fluff here and there being nonsensical.
Can remember someone saying that T-birds are flying tanks. I'm glad that you're with me on that question.
Well, here's the thing: a lot of our understanding of what makes a T-bird comes from Rigger 2 and Rigger 3. Here's what informs the idea that T-Birds have their engines inside their hull, or at least beneath the outer armor:
1) When designing a vehicle from scratch, the T-Bird hull is a distinct option from both Tilt-Wing VTOL and Fixed-Wing VTOL Aircraft hull frames. Ergo, a T-Bird *cannot* merely be a tilt wing or VTOL aircraft frame. It has to be something different.
2) Discussions of T-Birds in earlier books indicate their flight ceiling is pretty damn low - lower than tilt wing or fixed wing aircraft by a significant margin. If memory serves, the maximum flight ceiling for a light T-Bird is only somthing like 900 meters.
3) Every single picture of a T-Bird in any book, ever, has had the engines inside the hull. This has to count for *something*.
4) T-Birds get increased fuel efficiency during NOE flight, if I recall correctly? This may have been an optional rule, though.
5) T-Birds MAY be considered flying tanks, in that many tanks canonically referenced (such as the Stonewall) are ground-effect, vectored thust vehicles like T-Birds. I think t-birds are probably closer to IFVs, though.
6) The proper name for a thunderbird is "LAV", Low-Altitude Vehicle. The OTHER slang for it is "Panzer", as in flying tank.
I mean, yes, it should grate on your nerves that thunderbirds make no goddamn sense in terms of flight dynamics. None. But here's the thing: the thunderbirds/LAVs of Shadowrun - as well as Riggers in general - come from the novel Hardwired, by Walter Jon Williams, which is about smugglers who wire their brains (through "data ports" in their skulls) directly into hovertanks (called LAVs, Panzers, or Thunderbirds) to smuggle cargo in said tanks across a balkanized countryside.
So really, they have nothing to do with believability as they do with being an homage to this novel.
Edit: Using Banshee LAV stats from SR2, they hold 7500 liters of fuel, and have a fuel economy of 0.05km/L. This gives them a range of 375 km on a full tank. If they have been modded to accept external tanks, I think you can bump this to 12,500 L (2 external tanks of 2500 liters a piece), or a total range of 625 km. Compare this to the Lear-Cessna Platinum II, which holds 1500 L of fuel, and has a fuel economy of 0.5 km/L. Or a range of ... 750km. For a supersonic jet. Similarly, the BMW Blitzen has a max range of 297.5 km on a full tank of 35 liters.
Yeah. Fuel efficiency stats rarely match up with any sane estimate.
