Version 1.1.4
Changes since 1.1.1:

Version 1.1.4 Release Notes:

    Add menu item allowing deleted flights to be restored to the flight sheet (deleted flights are only retained in memory and will be lost if the program is restarted). (per J. Ashford)
    As part of the "restore deleted flights" feature, flight numbers are never reused. That is, deleted flights leave a numbering gap in the flightsheet that can only be filled by restoring the deleted flight. Note that the printed flight sheet will always have consecutively numbered flights in take-off time order (see below).
    Fix bug where printed flight sheet was not always in take-off time order. Program now automatically sorts by take-off time before printing.
    Show "non/club" in estimated cost column when the pilot(s) are not club members.

Version 1.1.3 Release notes:

    On first startup of the day (i.e. when flight sheet is empty) the program launches with a login splash screen that explicitly asks for a clerk name and airfield.
    Improve the wording of the dialog text for moving flights when changing airfields ("Keep on old sheet" or "Move to new sheet").
    Update documentation.

Version 1.1.2:

    Allow user to move flights between airfields when changing flightsheet location and date. (per L. James)

Version 1.1.1:

    Fix bug where winches as tow sources were not recognized as a winches.
    Show billing information only when club pilots are involved in the flight.

Version 1.1.0:

    Add estimated cost of flight to flight sheet (per J. Farrow).
    Show both Tug Down and Glider Down buttons after takeoff (needed when glider lands before tug, per J. Buchanan).
    In daily statistics at bottom of form, show separate totals for club and non-club aircraft (per J. Ashford).
    Allow club initials to be specified in settings dialog (affects sorting of pulldown menu entries for pilots and aircraft). Default is GGC.
    Remove dependencies on .Net 4.5, go back to .Net 4.0
    Clean up code for using lists loaded from .csv files.
