They found out the hard way that the bomb itself wasn't very
jettisonable... IIRC, during a test one got caught in the aircraft's
slipstream and started following the plane around until it reduced its
speed enough for the bomb/fuel tank assembly to fall clear...it also had
a tendency to slide out the back of the aircraft during catapult launch:

The aircraft promptly got changed into a recon machine.
