Image Overlay Inside with GUIDE built GUI (With Moving Animation based off given points)

I am building a GUI for class, that maps airports (recognized by ICAO codes), I have it to the point where I can show a map (just a simple image) and then zoom around the airports given so they don't see the whole map. I am having two problems. I wanted first to make sure the image fit into the desired axes which is pretty big, but that isn't the biggest problem. The main problem is I want a plane image over the map that starts at the first airport and flies to the second point, which can change depending on input. I did hard input for the ICAO codes at first, but I was trying to hold the image, and then show the other image, but it seems as if i need to share their 'Xdata' and 'Ydata', but when I try to get their xdata or ydata I run out of memory, and I am unsure if that could even work. Ideas on how to get this to work, or other approaches would be great. I can get it to display the plane, if I create a separate axes, but then I can't control the flight of the plane since it is based on a map in a separate axes.

This code was done in the opening function of the gui just for test case purposes.

axes(handles.map_axes);
imshow('chicago_sectional.png');
axis image
axis off

%TESTING BELOW
%test example of how the string %should be before being inputted
airport_list = ['KLAF';'KORD';'KOEB';'']; 

%Purdue Airpoit - KLAF
%O'Hare - KORD
%Another Airport - KOEB

%gets a box for map and x/y from custom made function that loads a database
[box, x, y] = database_grab(airport_list); 

%sets axes to box around all icaos codes
axis(box); 

line(x,y,'LineWidth',3,'Color','r'); %draws lines between points

%x is a vector of x coordinates [x1, x2, ..., xn]
%y is a vector of y coordinates [y1, y2, ..., xn]
%here i want to load 'plane.png' and have it fly from (x1,y1) to (x2,y2) and so on
%this should be done on top of the map and lines already displayed
