Formation Flying Planes and Hot Air Balloons

Below is the UE4 Blueprint Visual Scripting code to make the hot air balloons fly automatically but without artificial intelligence i.e. it does not avoid colliding with other objects.

As a computer science student, I was taught to not write "spaghetti code" which in the old Fortran days was hard to avoid thanks to the infamous but infinitely useful GOTO statement. The following visual scripting specification is not structured code.
