“Exception could be a Piper Cub, known to fly like a kite.”
Can’t remember who, but there was a guest on Johnny Carson once who was talking about flying in a Cub from Palm Springs to LA, and they were laughing as he described watching cars on the highway passing them below and leaving them behind!
The wind speed towards the west in the banning pass typically gets up to 50-60 miles an hour. Piper cub cruises at about 75 mph. So effectively the ground speed would’ve been 15 mph.
