I concur with SB; I think taking off with too much flap (or no flap) is one thing (and as they say let the man without sin cast the first stone etc etc) but taking off with concrete tiedown blocks is quite something else. Just how dim does a pilot have to be to do that??
However, I'd like to know how recently he got his PPL and (if recent) who the instructor was. Might be quite interesting.
