This is a really cool idea. I'm also looking for information on some flights that are not in BTS (regional carriers.) Flightstats has proven to be my main source, but my IP is now banned pending review due to alleged scraping (apparently searching more than 200 flights is cause for a temporary ban.)

Would someone be able to help? All are delta marketed numbers and I'm looking for tail numbers.
