For whatever it's worth, on twitter Chuck Yeager has said he wasn't a fan of the Avro Arrow. He didn't go into details though. He's well into his 90s, so maybe he doesn't remember the details anymore.
Eh, maybe. But neither could the F-104 and he liked that plane. But the F-104 was also an American plane, so maybe that has something to do with it. Then again, he almost got himself killed in a rocket boosted NF-104.
