21-prvi B-2 bombarder je stradao u polijetanju .23.02. 2008 godine u polijetanju iz USA AFB Andersen iz baze na otoku Guam. Postoje snimci na youtube-u.  B-2 svoja svojstva "nevidljivosti" zahvaljuje osim specijalne boje, premaza , koja je usput jako osjetljiva na vlagu tako da se ne koriste kada je prognoza kisa u zonama djelovanja, zakrivljenom obliku trupa i krila+ nedostata kormila pravca kao velike povrsine za vracanje odbijenih radarskih valova i povecanja radarskog odraza RCS, hladnim ispusnim mlaznicima tako da je slab odraz za rakete i senzore infracrvenog i toplinskog spektra svi polopci su tzv. Anti-Radar Panels, ali najveca tajna koja se pazljivo skriva je da avion ima tzv. plasma generatore koji stvaraju neku vrstu plazminog omotaca oko aviona tako da se radarski valovi ne odbijaju i vracaju od aviona nego se "upijaju" i tako avion postaje nevidljiv za protivnicke radare.Tada je avion u nekoj vrsti Ionizirajuceg oblala , plazme . Postoje slike B-2 u takvom oblaku npr. fotografije napravljene u letu od Bobbi Garcija snimljene iz F-16. Kada se ukljuce ti generatori plazme se na napadnoj ivici krila koja ima na svakom krilu 8 panela ,svi paneli osim drugog panela gledano od nosa zrakoplova, koji ostaje ne elektrziran sa visokim naponom i to napadna ivica je "+" ionima, a mlaznici izlaza plinova i turbomlaznih motora 2+2 su negativni "-" ioni velikog napona. Drugi panel gledano od nosa na krilu je ostavljen elektricki neutralan jer sluzi kao radarska antena, bolje reci ploca sa puno malih antena radara, koji se i onako rijetko ukljucuju da se ne oda prisutnost aviona. Radar nema klasicne rotirajuce antene nego tzv. Phased Array Radari. "For reasons not yet de-classified, the B-2 charges its leading edge to a very high electrical potential difference from its exhaust stream. It has been suggested (by Jane's Defence) that it augments the B-2's low thrust main engines. It is also a well known phenomenon that an ionised gas (plasma) will scatter a radar beam far more effectively than a solid surface of any conceivable shape. This could be the purpose of the high voltage leading edge." "Plasma stealth is a proposed process that uses ionized gas to reduce the radar cross section (RCS) of an aircraft. Interactions between electromagnetic radiation and ionized gas have been extensively studied for a variety of purposes, including the possible concealment of aircraft from radar that plasma stealth theorizes. While it is theoretically possible to reduce an aircraft's RCS by wrapping the airframe in plasma, it may be very difficult to do so in practice. Various methods might plausibly be able to produce a layer or cloud of plasma around an airframe, from "simple" electrostatic or RF discharges to more exotic possibilities like laser produced plasmas." Zato osobno sumnjam da je srpska protu-vazdusna odbrana oborila B-2 kako se cesto senzacionalno navodi. Od 21 aviona ostala su 20 jer je jeda izgubljen u udesu, a nije oboren.
O zastiti sa ioniziranom plazmom se malo pise nego se uvijek navode ostali stealth aspekti. U casopisu Air international od Januara 2000 se u clanku "Military Power" navodi pri kraju clanka nesto na tu temu ali se kasnije to vise ne navodi. Imali netko malo vise podataka o tome??

Novije fotografije akcidenta pri sletanju američkog bombardera smanjene radarske uočljivosti B-2A, prilikom sletanja u američku vojnu bazu Whiteman, pre nekoliko meseci, tačnije 14/09/2021. godine.

Ako nemoze radar moze Google maps da upeca B-2 u letu iznad SAD-a.
Lokacija: Misuri, Kansas City (50 milja istocno).
