One of her "friends" said she did have a fear of flying...
Kate DeVarney, one of Kavanaugh’s friends, told the outlet that Ford “really has a hard time being in a place where there's no escape route." She added that Ford did not like to fly because an airplane was "the ultimate closed space where you cannot get away."
...which the article also stated was due to the alleged encounter (notice, though, no evidence)...
On September 23, CNN interviewed friends of Ford who claimed she had a fear of enclosed spaces that didn’t have multiple exits, such as a plane. These friends were allowed to claim, without evidence, that this was due to Ford’s alleged encounter with Kavanaugh 36 years earlier.
...while her ex's sworn testimony said otherwise.
On October 2, an ex-boyfriend of Ford’s sent the Judiciary Committee a sworn statement claiming Ford never expressed any fear of flying — even in a small propeller plane — or “a fear of closed quarters, tight spaces, or places with only one exit.”
So yes, there certainly is a contradiction. And, as I said, if someone was interested in pursuing this further, there was more to go on than the actual allegation which started this whole thing.
No, I'm suggesting that her "fear of flying" is not real, as the evidence of her travels and a sworn statement from someone who was intimately involved with her for a period of time in her life. Two credible evidences. Even if it were real, the claim that it was Kavanaugh's fault is without credible evidence to support it. Either way, Ford's overall credibility is diminished, IMO.
