As the Ospreys entered the LZ for the second time, they were met with an overwhelming volume of enemy fire.
Sort of like the circumstances of the F117 shot down over Yugoslavia, no? I dont think anyone argued against stealth technology itself as a result there; it came down to operational tactics.
The arguments with respect to V22 about insertion and survivability based upon swift infil/exfil are still 100% valid. In fact, its probably what helped reduce time on ground in this instance.
Not to mention, if we harken back in the depths of the V22 threads, I suppose this goes to demonstrate some usage of the V22 in the line of fire (not being withheld from dangerous tasks), and sustaining battle damage. There are many more incidents like this whose reports are not in public domain.
