Flying Low, REALLY LOW

So when we got on the errant 747 up in the jungle town of Iquazu, there was a lot of mixxup and confusion about which gate (difficult at an airport that only has 2 gates) and when, and where did a 747 load of people come from? and why was this plane flying on to Buenos Aires with only about 20 people on board? But anyway, the preflight announcements came first in Spanish, and then in English when we learned that we were going to be flying at an altitude of 37 feet. This was disconcertng when we were on an airstrip in the jungle surrounded by trees in excess of 100 feet. But I guess the pilot knew his way through the trees cause we didnt hit a single one all the way to BA.
