That’s casted aluminum and is the actual frame of the vehicle I believe. Check out the jerryrigeverything video where he breaks the frame on one of these, I think it’s the same stuff. Super thin cheap foamy casted aluminum so cheap it looks like plastic.

They said this before Vietnam and it was wrong. Ironically if truly stealth fighters with low radar and ir profiles were to engage each other in the air they would probably end up using guns primarily again as radar/ir guided missiles wouldn’t be reliable in this event.
No he’s right. The solution for an optimal surface area to volume ratio is a sphere. The farther you deviate from a sphere the less optimal you become. The actual math for this is finding deltaSurfaceArea in respects to cylinder radius for a given volume and then finding the maxima, which is a Uni physics 1 problem I really don’t feel like doing. Long story short, optimal is when height = diameter, or as close to a sphere as a cylinder can be.
The whole LHC making black holes topic is so silly because if something the energy level of the omg particle hitting the atmosphere doesn’t create a planet destroying black hole, then nothing humanity will ever create with particle physics will.
Just the radiation from the sun going through the Van Allen belts is higher energy than the LHC and the omg particle was like 7 orders of magnitude higher.
