Sad news indeed. G.I. Joe had a great voice cast, with each actor bringing life to each of the characters they voiced. Some of them, like Michael Bell and the late Chris Latta I'm familiar with, but despite what a distinct voice and personality Mr. Hostetter gave Bazooka, I never knew who the voice actor was. Seems like he had a diverse and successful career.
Mr. Hostetter, like so many of his brethren, are a part of the soundtrack of my childhood, and so though I'm just now learning his name and a bit about him, I'd like to take this moment to thank him for helping to make my childhood one of wonder. R.I.P., sir.
