JBD,
In case you're not familiar with what they are, watch the "cheesy" movie "Top Gun". At the opening of the movie when all the flight ops are being shown, you will see an F-14 go into afterburn just before launch. If I remember correctly, they show the JBD's lifting out of the deck. There are big deflectors used to keep the flight deck crew from being blown overboard.
Regards,
Doc
