Yes Greenshirt, Yes, Yes, Yes;
1)The B-2,
2)Pant & coating stripping,
3)It doesn't damage the many composite & sensitive surfaces, it's environmentally friendly.
During block 30 upgrade the B-2 is stripped of all its paint, RAM & coatings so that its stealth profile can be brought back to where it should be. Northrop-Grumman have developed a patented process (Envirostrip) to carry this out, using crystallized wheat starch & compressed air. The first completed airframe was AV20, spirit of Pennsylvania.
The most prominent contributor would be Jack Northrop, who was shown design drawing & models of the A/C before his death in 1981. The A/C has become news worthy on more than one occasion, with confidential information apparently being passed to both Russia & China.
On a trivial note, as most will probably be aware, the rendition of the B-2 cockpit in "broken arrow" was whatever the next thing after pathetic is.
Interesting A/C, but still prefer the SR-71 though.
Greenshirt, the floor is yours.
