BS, a hearty I'm with you on this one!
If I remember the original query on this subject it was can you do it? I don't know, as I have never flown a Boing product. I do fly a Saab, however. The Saab manual specifically recommends a wing down landing, which if I understand anything means a forward slip technique (or else an ealiy arrival at the terminal). Maybe the Boing manual has a similar paragraph?
On the subject of 'slips'(aeronautical): as far as I can work itout there is little to choose aerodynamically between the foreward and the side versions, but do any of you remember slipping and sliding turns (not enough rudder/too much rudder)? You are all going to lose your medicals to ulcers if you don't relax a little.
