Whitley test "produced a failure at 98% of the design load" is that good?

Point IV is advaisable in many planes. Using powerful trim tab to get out from high speed dive easily overloaded a plane.

For natural reasons AA guns and night fighters early in the war were concentrated to S/L zones, not much idea simply get the plane into S/L cone and note "there it goes". Especially for night fighters operating at S/L zones time was paramount. They must see the target, position themselves for the attack, attack and shot the bomber down before it departed from the zone to the dark night.
