So....The persons inside the al. frame are subjected to volcanic ash...
No 'contamination' as such...the guys up at the pointy end would soon descend out of the plume 'lest the 'noise' stop.....
But, unless the 'noise' does stop - then nobody dies.
Then the persons inside the al. frame are subjected to 'Shudder'...Radio Active Contamination...and they are breathing the filthy stuff, and the Al. airframe is affected....
To What extent..?? I wonder..??
I understand the time of exposure and the degree / strength of contamination is the key issue...but...
Will you still be able to have 'normal' grandkids..?? I wonder..??
OVAH!!
