Lucky vs Luckier

There were two people who went exploring and they reached a swamp. Now, the first was a man of means, and so he called in for a helicopter and within a short period of time, he was on the other side; the crease on the pants of his Safari suit were intact. He even took some photographs while he was flying over. He was a man with an avid interest in the sciences, and he made a modest but significant contribution to the field of swamp study.
