You made me laugh out loud at a feature that I had not discovered before. You have made lots of improvements to mouse-hover tool tips, but I noticed one on the page for a specific aircraft that is the funniest.
If you let the mouse hover over the registration or flight number on this page, the tool tip gives you the phonetic pronunciation of the number. I.e. for N5943U, the tool tip says: “november fife niner four three uniform”. Now I thought it was funny that it popped up anything at all, but when I noticed the “fife” and the “niner” I had to pick myself up of the floor! You guys crack me up!
The street address is cute, too. Somebody is bound to ask for it if you didn’t already have it in there.
While on the subject of the tool tips, I really do like the one where I get the city and state when I hover over an airport name. An airport’s location isn’t always apparent by its name. Something’s wrong with KILN, though. Apparently don’t have the city/state in your database, never pops up anything. Neither do airports outside of the US, but I really don’t care about them.
