Sorry to "spoil" the party, but WTF (or should that be HWF ?) did we (having UK nationality I can't say they) ever certify this thing as a multi engined aircraft if the only purpose of the 2nd donk is to prolong the glide ? & the trislander ? ? jeezuz, the CAA was REALLY cheap to pay off in the past, or was/is EVERYONE involved in UK aviation in the Masons ?
Edited to say, RTFQ2 . . . if I had read the report properly I would have seen that SE performance was the least of their problems Duh !
