OH-58D flash cards to help aviators study their operational limits and emergency procedures.

此版本中的新功能：

The scroll bar has been replaced with the ability to scroll the text itself. The text resizer is easier to handle. Swipe capability has been added. Because the text box is now scrollable (instead of using a scroll bar), you have to swipe on the sides of the screen, above, or below the text area. Swipe up or down to flip the card, swipe left and right to go forward and back. Finally, the layout has been overhauled due to popular demand.

Special thanks to Z-Design for the Photoshop brushes.
