@Phosphenes @ComicContext Been decades since I've looked at that issue but as I recall, there was a plot to gas a bunch of people (maybe during a political rally?) from a hot air balloon. Capt America (as Nomad) and SHIELD were after Viper -- who I don't *think* was with Hydra at the time. While they were running to the balloon as it was lifting off, Dugan suffered a stroke, which is what you see in that panel. Don't recall the issue number but it would've been around 1984 or so.
