As I'm reading these threads down here in the basement den,I'm staring up at a B-17 on a flying calendar.It's an all aluminum colored aircraft and it's name is "Aluminum Overcast".The rear tail fin and wings are painted red.It's a "G" model.The serial number is " 30H",and it travels all over the USA.Could this have been the plane you saw Bill or was it the Collins Foundation aircraft.I think theirs is painted green with a cloud colored underbody ??
