I’m thinking .50 caliber incendiary would make VERY short work of anything using hydrogen lift gas. And now I want to see zeppelin kill markings on the side of a P-47.

Thanks to reading acres of fascinating rigid-airship posts by someone*, I learned that shooting down a hydrogen-lift device was far harder than it would appear. If memory serves (a pop quiz!) regular ballistics could make holes, but not ignite the gas. Tracers could also make holes, but passed through the envelope too quickly for enough oxygen to enter the envelope in sufficient volume to cause ignition. It was a combination in the belt, of relatively low-velocity rounds + tracers with a long, slow burn that did the trick. *Nebakenezzer PainterofCrap fucked around with this message at 15:17 on Apr 19, 2020 |

Yeah, iirc it was .45 Gatling that eventually worked. A .50 would just zip in and out with very little effect other than making some holes

Elviscat posted:I think about this a lot, as aircraft are the only means of transportation that isn't easily directly or indirectly powered by clean, environmentally friendly atomics, in my vision of the world that has virtually no pollution based on this incomparable, but vilified green energy source. Unreal_One posted:It can be expressed in kW, but for large aircraft, quite a lot of kW. Conservative guesstimating has a 747 needing way over 100kN in cruise at a speed of ~250 m/s. That's 25,000 kW. This is helped by the fact that jet engines get more efficient with speed, having a thrust that drops off much less than linearly with speed, even if the plane as a system gets less efficient, since drag power increases with the cube of speed, even without the nonlinearity of supersonic. Thanks for indepth posts, guys. I read them and said "twenty-five Megawatts to fly a 747?!" and then crossed nuclear propulsion off the list. I'm adding to the list "6 GE90s". Elviscat posted:If you want a heavy-lift aircraft that doesn't burn fuel, it's airship all the way, mount it high up on the envelope and away from the gondola, and you need much less shielding, because radiation fields decrease in strength with the square of distance. As you can tell, this was a long-con to talk about airships* *lies

This image has the vent on the opposite side but who knows what model they have.  The only other possibility I can think of is something to do with one of those wacky gas-fired cabin heaters and I can't imagine a 2005 model 182 having one of those.

They had the jet on a very low power setting for the actual stunt. The extras where they’re tossing random poo poo, the jet was at a much higher throttle setting.

In regards to shooting down Zeppelins in the 1940s - even if regular high velocity ammunition did not work that well, there's always the 3.5 inch forward firing aircraft rocket. I bet eight of those would do the trick.

Zeppelins are hard to shoot down in the scenario of “they’re our boys with war tubas heard them crossing the Channel and they need to be stopped before they bomb London. P.S. There’s fog.” They are not hard to shoot down if you catch them in the open ocean, and you will because they have the RADAR profile of the Great Pyramid.

I guess the P-39 might have had trouble performing at altitude but it ain't like the Zeppelin is a performer at altitude. Service ceiling is 35,000 ft for the Airacobra, which is well above the practical service ceiling of a Zeppelin, I think.

BIG HEADLINE posted:From what I've heard, L-39s are deathtraps. An evolved form of the Bonanza, only it kills senior executives, not rich doctors. One of the more surreal experiences at work was when a contracted L-39 for some jammer tests was doing its final flyby on the way to land, doing a 500 feet AGL formation hollywood pass, and lost the engine. On the deck over a sea of mesquite berms is a bad place to lose an engine, but fortunately, he had a lot of speed still. The flight lead was still a few thousand feet up and spotted a disused UAV dirt strip, but no one had the fuel to really see if he was able to zoom climb and then make the landing. Plus he lost UHF when his electronics failed while still trying to deadstick line up on the dirt strip. Meanwhile, we sent a HMMWV hauling out to the last known radar contact before we lost track. We ended up screaming down the highway at ludicrous speed and were a couple miles out from this dirt strip when the pilot sent a selfie to the project lead with the former fighter pilot looking like he was so fuckin' psyched and the non-military, non-veteran engineer/jammer operator looking like he was still at risk of dying from a heart attack. I assume they had to take the plane apart and ground haul it out or something... It was not a big strip.
