I first played this game on an HP-25 calculator back in 1976, using the same formulas as the article explains.

I played it on a hp97/hp67.

Memory hazy, but I think I used the inbuilt calculus features of the calculator to get a perfect landing with a burn of 45 (about half the fuel) on say turn 12.

I had no prior expectation of what the optimum burn was and certainly had not heard of a 'suicide burn'.
