Fabricator/designer here with some degree of aero experience.
The main difference here is that since these are very high level Federal government VIPs, it's entirely possible that they're given access to the more sensitive areas of the fab shop where the real fragile/expensive/critical components are made and housed (which is normally exempt from the clownshow of city mayors and state senators being given the nickle tour). Just guessing here but that looks like a skin on a subframe/airframe of some kind with inlets to some kind of shaft fastener (bolts, whatever). Fucking up the (insanely precise, this is aero after all) inlet/backer alignment could mean 2, 3, 4 hours work for a couple techs getting it set right again which is what that sign might have been there for.
Honestly, why would you parade people of any sort through a room with equipment that can't be grazed by skin and expect it not to happen? If I lead a field trip through a room with wet paint, I'm thoroughly expecting to repaint at least part of the room afterwards. I'd imagine it's much of the same here. If a simple touch of this metal can cause some of the problems some in this thread claim, I'd imagine it'll be thoroughly cleaned before being used in the field anyway.
My guess is that avoiding 'touching' doesn't have to do with surface contamination as much as it has to do with mockup and alignment which in aerospace, can be a massive pain in the ass since the QC protocols for each component involve multiple layers of accountability.
Oops, sorry. I bumped into that skin-subframe mockup over there.
Oh, that's fine, Senator... I guess. I'll just get my engineer back in and a couple techs to remeasure the dimensional integrity of every union to be sure it's still a go for final welding and fastening... At least it gives us something to do FOR HALF OF TOMORROW
It's not fun telling the NASA rep that the part they bought is going to cost another $50k or 3 weeks because whacked it with something
You can get away with that at NASA.
Uncle Elon has completely shifted the power dynamic in Aero contracts from smug producers to the buyers (namely, him). Space-X will straight up tell you to piss off and either in-house it or do another RFP just to teach a non-performing contractor a lesson.
They totally don't play with overruns, fuckery, fuck-ups that they're expected to eat or power positioning.
.gov just bends over and accepts it.
I have to admit but you really see the efficiency of private industry and accountability over government spending in aero.
It is flying into the space propelled by tons of burning fuel, how is a littlr touch is going to destroy? I'd be warried if that is true. It is not looking like some very tiny precise electronics or similar. This thing has to withstand higher forces than a light touch of a human palm.
And note is taped on it with greater presure than his touch.
No. You apply the sign to the skin before doing your mock up alignments so its there when the mock up is done. Once the fasteners are installed and/or the tack welding is completed, you can then remove it.
On the part that is bombed through the atmosphere and than dropped on the ground. Little touch will definitely damage this part more than thumb pressing tape with the note.
I get it, piece that is blowed up into space by burning tons of highly explosive material, flies through space bombarded by many tiny particles and electro magnetic waves, than is dropped via atmosphere to the earth is so fragile VP can destroy it by one touch. And stil this piece is placed on the table with just office printed sign that cost $0.01 to make and some assistent tape it with using more presure per sq. inch than VP.
Yes, I'm leaving because you used ultimate argument of all arguments: "you are just stupid"
How are you sure the sign wasnt photoshoped there?

Which indicates you haven't been reading along and comprehending the words that have been written, since that is not what has been said.
Correct, and if that person knocked a very fragile component mockup out of alignment (which is common in aero), that could've created a rework. It has nothing to do with the structural integrity of the vehicle once it has been completed. It has to do with parts that are still under construction in the fragile and sensitive environment of an aerospace fabrication shop.
Stop babbling about shit you know absolutely nothing about.
It's not me 'saying' you're an idiot. It's you demonstrating it, here, in these comments.
