"""Flight times"""
# A flight was scheduled to arrive at a particular time, 
# but it is now estimated to arrive at another time.

# on time, early, or delayed.

# Times are represented as floats, for example:
# 8:00am is represented by 8.0
# 2:30pm is represented by 14.5

# Write a function that gives the flight status 
# given the scheduled and estimated times of arrival.
