Can I use

@Thederpingmemes What?

Wait@SledDriver

Okay@SledDriver

@Thederpingmemes OK, well, let's just agree to disagree.

And their reinforced too and their still not square @SledDriver

Well if you look at it it is slightly curved@SledDriver

@Thederpingmemes It's certainly possible (plenty of cockpits have square panes), it would just take some effort and have a weight penalty.

A simple solution would be to reinforce the square corners. Another way would be to have the window pane extend past the square frame, so that it looks square while having rounded corners.

These solutions would need extra material and thus weight, so they're not optimal, but it certainly can be done.

It was kinda meant as a joke and in reality it’s not possible @SledDriver

Two fatal crashes in 1954 - Flight 781 from Rome and Flight 201, bound for Johannesburg - accounting for 56 lives, were found to be the result of structural weaknesses in the fuselage, caused by dangerous stresses at the corners of the square windows. The harsh angles meant that the surrounding metal experienced pressure two to three times greater than elsewhere in the cabin.

A number of inquiries into the crashes highlighted metal fatigue as a key cause of the fuselage breaking up, prompting de Havilland to modify the design of its later aircraft, introducing the stress-alleviating oval windows that we see today. The company also increased the thickness of the Comet's fuselage walls.

@Thederpingmemes Square windows are certainly possible. Furthermore, just because the holes are square, doesn't mean the windows have to be as well -- anyone who uses this can fill in the square holes to get whatever shape they want.

Same amount of parts as my Boeing engine@SledDriver

But planes can’t have square windows or it will crash @SledDriver

@Thederpingmemes Because that's what was agreed upon.

Why square window

Wow time to build a bomber

Thanks, @KerlonceauxIndustries @FastDan

nice

Wow,this looks epic.

Glad you like it, @chancey21

Man this is great
