You would, I wouldn't, always better one gear than nothing (text book)
Arc-en-Ciel
Theoretically,yes.But as max Angle says,flying isnt covered by a book.In this case,the belly landing worked..to perfection.One main gear down(as recommended by the book) may or may not have been so propitious if that had even been an option..The nosewheel collapse in the Gimli incident was a "fortune in disguise"...so a Captain has to consider these options that arent covered in the "book"..a deliberate all main gear UP landing over one main gear UP or a nosewheel UP landing with both main down as a deliberate tactic in the event of total hyd fail on a limiting runway.Its not in the book.Its airmanship.
