To state that something is unimpressive whilst sitting on the sidelines looking in and without having attempted anything similar oneself seems neither valid nor particularly mature to me
So what do you find impressive about it
MaxR? I find it unimpressive because of the very fact I do know what is involved. I was very closely associated, not as a participating crew member, with a successful 1971 round the world speed record attempt, and also the 1969 London - Sydney air race (Bonanza A36). Same pilot in both cases, with different second crew member.
