zeewolf help

long time ago on my amiga i aquired a demo of zeewolf and got a lot of pleasure playing the level it had on it.
Lately i've been playing an emulated full game but have no game manual.
In the third ? or fourth level you need to carry another aircraft back to the mother ship.
Can some one please tell me how to pic it up as i've had no luck with any thing i've tried and carn't get any further in the game, most annoying.
thanks
loopy

On our main site we don't have a manual but a game guide, perhaps you'll find some help in there:
