Assuming this is going to be sitting in a direct sunlight, I’d personally do a double take on the ventilation. That single vent isn’t going to be doing much and it’s going to get hot in there - especially with the dark paint.

They seem to approve of my method

Virtually every single time I start designing something in sketchup I realize that the way I planned it in my head wouldn’t have worked. I’ll much rather make that mistake then than once I’m fitting the parts together. The accuracy you can get this way is also quite amazing. When I check the final measurements once I’m done I’m usually off by few millimeters at most.

Free version of SketchUp - it’s great for stuff like this.

I used these yesterday for adjustable legs on customers’ bathroom counter.

Is this a joke?

Yes.

Oh, well, for it to do that, it would need to be able to detect an incoming missile.

It does have sensors that look for the heat signature of the missile’s rocket engine. There should be alarms screaming in the cockpit, the plane diving and doing pirouettes with flares flying everywhere. I don’t know why that doesn’t seem to be happening - maybe the video isn’t real.

You can see in that video above just how well that “IR masking” works. The shape of the plane is barely distinguishable against the sky.

There’s only so much you can do to hide a plane from heat-seeking missiles. The best bet is to try outmaneuvering it and confusing it with flares.

They suspect it was hit by a Qaem-118 ground-to-air missile fired from a pod on the back of a pickup truck. These things only have about a 25 km range and are mostly designed against drones and helicopters, so they pack a smaller warhead - which is probably why the plane was able to fly back home.

And for anyone wondering how a nation like Iran could hit the world’s most advanced 5th-generation stealth fighter: with a heat-seeking missile from short range. Stealth mostly protects against active radar, whereas IR radiation is something the plane itself emits (heat). It may not be enough to detect from hundreds of kilometers away, but this was apparently much closer.

With a miter/circular saw. I’m physically unable to cut straight with handtools. Even if I use a square to make guide lines around the entire piece.
