Stereotyping? Sure. I think the video gets across certain points. As a young flyer, I have no real grasp about what it takes to get my aircraft FMC. So I have no idea why there never seems to be spare parts for my 45+ year old airplane, and why there is never a spare despite dozens (or a hundred) sitting on the ramp without engines turning. Yeah, I know the guys working the line are busting their ass in shitty weather, and I give them credit...I doubt those guys are the limfac.
It's frustrating being limited in our ability to execute the mission. So, for me, this video really addresses that there isn't a productive dialogue between the Ops/MX (even shoe clerk) world on why the mission is getting hamstrung for lack of spares, parts, and goddamn vouchers.
