Wow, was that dumb! The plane was over loaded with four big adults, dirt runway in the mountains, hot mid-day and a high density altitude. Doesn’t get much worse than that. Oh, except that he had the mixture knob all the way in (full rich) a definite no no when operating at high altitude. When the plane lifted off, settled back on the runway then lifted off again that should have been the pilots clue to abort, but no he just had to keep going. Lucky they’re not all dead.
