Excellent post! I agree wholeheartedly, I have witnessed a few close calls before too, and they were also a result of people flying aircraft they shouldn't be flying quite yet, work your way up to these fast planes and big planes slowly and you will be richly rewarded with many a fun safe flights. Also checking over the aircraft after each flight has saved me many probable mishaps, every time I find something wrong or out of place, it re-assures me that checking is a great idea.
Just my 2 cents.
