I would like to request adding streamers when planes pull high-g's. I am pretty sure WWII planes did make these.
I read a book about P-40's in the flying in the Flying Tigers in China, "Tiger over Burma" or "Tiger over China" or something with Tiger in the title. A quote from that book went something like this:
A P-40 was in a dive and almost crashed, but pulled hard on the stick to prevent this. Some of his buddies saw this and noted the huge streamers created by the P-40. On the day following this event, one of the squadies who witnessed the high-g streamers flew over the same site a day after the P-40's high-g pull out (the pilot who created the streamers didn't attend the mission the day after). The squady approached the one who almost crashed and mentioned to him "Hey so & so, we flew over the site where you created those huge streamers yesterday, and wouldn't you know they were still there today!!!"
P.S. I think streamers depend on the altitude, humidity, dew point, etc... So, HTC creators may need to some research on the subject.
