assuming you have the x,y plane as the ground, then all you have to do is to increase the height of the object, eg:
sync on
sync rate 40
make object cube 1,1
make object plain 2,50,50
pitch object up 2,90
position object 1,0,0.5,0
position camera 25,10,25
point camera 0,0,0
color object 2,rgb(10,150,50)
sync:sync
wait 1000
height#=0.5
speed=0
do
height#=height#+0.1
speed#=speed#+0.004
if speed#>1 or delay<40
if delay=40
delay=0
endif
inc delay
height#=0.5
speed#=0
position object 1,0,0.5,0
endif
position object 1,object position x(1),height#,object position z(1)
move object 1,speed#
sync
loop
just creates a loop where the ultimate combat cube does a VTOL takeoff and flies off, to be replaced by another, and another, all it does is increase the height of the cube and accelerate it forwards by a small amount each frame, hope thats what you want.

PS: this was written in Pro, you might need to make small alterations although I tried to keep the Pro only commands out.
