I tried sending it to X3D Validator via url
but it didn't eventually return. Scene is fairly large (2.8 MB) so testing will be easier on a smaller excerpt; perhaps include same number of values but only use 1-2 places beyond decimal point for file reduction..
I also ran X3D Validator in Netbeans using X3D-Edit and got the following:
--------- Commence validation checks for ifs.x3d ---------

Well-formed XML check: pass

[X3dDoctypeChecker] success: valid XML declaration found; success: final X3D 3.3 DOCTYPE found.

It is good practice to identify editor used, for example <meta name='generator' content='X3D-Edit, https://savage.nps.edu/X3D-Edit'/> [/X3D/head, info]

It looks to me like your normal value is failing the regular-expression check for MFVec3f in X3D Schema.
Am noticing that many of your normal values are greater than 1, you likely want to convert all normal vectors to 1.0 unit magnitude (and none with 0.0 magnitude).
FYI there was once a regex in place that only allowed such unit-magnitude vectors; I disabled it because many tools do not bother to normalize that content. Perhaps we should have a strict mode in X3D-Tidy for that.
For you a good generator meta tag might be something like the following (I'll restore the meta/generator menu in X3D-Edit).
<meta name='generator' content='X3DJSONLD Loader, http://coderextreme.net/X3DJSONLD'/>

A handful of players forgave the normal problem and showed a flat neon-green helicopter pointing straight down.
Others did not forgive. Xj3D independently noted the same MFVec3f error.

minimum support levels in X3D specification are pretty high (and there is no maximum):
X3D v3.3 Abstract Specification, B Interchange Profile, B.4 Conformance criteria
Table B.3 — Nodes for conforming to the Interchange profile
Item X3D File Limit, Minimum Browser Support
Color 15,000 colours. 15,000 colours.
Coordinate 65,535 points 65,535 points.
Normal 15,000 normals 15,000 normals.
all the best, Don
