I have being searching for ages for a film but do not remember the name, I am not sure if is from the 80's or very early 90's, I was only a child so I don't remember, the movie is about a boy and his grandfather who go in a hot air balloon and the safety rope comes loose, the boys father tries to save them by grabbing hold of the rope but the balloon is pulling him up into the air so he has to let go and they float away, the crash land in the middle of the countryside miles from anywhere and have to find away to get home whilst being stalked by a mountain lion, if anybody knows the answer I would be greatfull if you could help me out, many thanks!
