Very true, my BGO was a Captain, an F-4/14/18 pilot, Vietnam vet, base commander, etc., etc. and all he could do for his daughter was give her a Presidential nomination. She was actually notified of her appointment less than a week before Plebe Summer and she turned it down, went to U of A for a year, reapplied, and got in.
These next two stories are off-topic, but interesting (and very sad). Her best friend, however, got accepted, but the family dog bit her face the day before she left. She tried to get through plebe summer, but the wound was too bad to bear, so she had to go home.
My best friend's brother-in-law (his sister is five years older) was the highest-scoring candidate the year he applied. 1600 SATs, perfect GPA, sports, his dad was an admiral, he was the perfect candidate. He got in, had his first asthma attack during plebe summer, they sent him home, and he had to settle with Stanford.
On a different note, his dad gave me some excellent advice. He told me I would have a much better shot at becoming a navy pilot, since AF pilots don't retire until they start losing their dentures in their oxygen masks (he didn't say that word-for-word).
