# This function determines if a flight has landed outside the airfield.
# The perimiter of the airfield is taken as circle based on the designated centre point
# of a specified radius. This is not the most accurate but will do to start with.
# If a flight lands outside the airfield then an SMS message with there landing coordinates
# is sent to a specified number.

# This function determines if a flight has landed within the vicinity of the airfield take off point.
# If not it sends an email to the designated address specifying the landing coordinates, these
# can then be used by the recovery team to locate the aircraft using appropriate mapping technology.
# The algorithm used is that of a circle of defined radius centred on the originating airfield.
# The function is intended to send the msg either by email or SMS but at the moment only email
# is supported. The SMS code is included, has not been tested and requires an account to be created
# and of course each SMS msg would be charged to that account. The provenance of the SMS code is
# included if this helps with subsequent development.
#
# Returns: True - landed out. False - landed inside airfield limits
