Thanks, but does this article cite a source for this claim?  I've seen this claim in print a couple of times, and often repeated by armchair generals, but there is no documented case of an airburst RPG damaging a US aircraft, and I've never been able to find a quote from officers in Afghanistan/Iraq/etc. where they claim to employ this tactic.  Granted I haven't browsed Soviet military recortds, but I'd like to see some harder evidence before this claim is repeated as fact.
