Our pilot mentioned that we reached a cruising altitude of over 30,000 feet. This prompted me to think of the expression, “30,000-foot view”. It’s a business cliche to be sure, but it’s chiefly an English unit one. 30,000 feet is about 9.1 kilometers. I have never heard anyone say, “Let’s take a 9.1-kilometer view of this business plan.” This is far as I want to go on the phrase a 30,000-foot view. I wanted to keep it at a high level, just cover the mountain tops.
