First off, I have to say great job on the new historical flights feature, nice to see the hard work pay off so well.
When using it, though, I thought of a cool possible addition. It would be interesting if we were able to select more than one past flight at a time, and have the different tracks overlayed on each other, so you can compare them visually. Just throwing the idea out there. 
Thanks for the kind words! You’re definitely right – that’s a great idea. In fact, we already have it working on our development systems and are experimenting with different user interfaces for offering the overlay of various flights or date ranges.
You guys are always a step ahead. So when do you sleep exactly? 
I only sleep during the extra hour when we switch from daylight saving time to regular time.
