FYI, the name of the plane 5R-MFA is "BOINA", and not BOING. BOINA is the
region name around Mahajanga. So no mispelling from Air Mad (though could
have happened).

Ha! Who coulda thunk! You are absolutely right, of course. And I
need a new prescription for my eyeglasses

Also, the can flight attendants sprayed in the AF flight is some
anti-mosquito stuff. It is customary for any flight leaving a Malaria
infected country.

Actually, the spraying was on the Air Mad flight.
