I am interested in knowing how low the flight times can get for the numerous flights in the game, so I tried to collect my best times for all any% flights:

Airport to Construction site: 27s https://drive.google.com/file/d/0B38XMNjp-HeidnZMSWhQbDI3eW8/view?usp=drivesdk

Bait trap zone to Construction site: 31s #

"Backwards SAM takeoff" to Construction site: 33s (sloppy landing) https://drive.google.com/file/d/0B38XMNjp-HeiUjlPdjgwSF9jMnc/view?usp=drivesdk

Construction site to Car show room (e2g flight): 15s https://drive.google.com/file/d/0B38XMNjp-HeiV3F2NkdFbHpQMTQ/view?usp=drivesdk

Construction site to Exchange: 17s https://drive.google.com/file/d/0B38XMNjp-HeiQ1N1WkZRSlhMYXc/view?usp=drivesdk

Dodo bait is pretty irrelevant in this regard, but I think my best is a 49s (excluding the 4s grass touch)

If you have better times in any of these flights, let me know so I can try to get them myself.
