Wait, #Biggles has to make a (quite uneventful) forced landing because *the* magneto failed? Singular?

I ges things do change in aviation.
They took of in a hurry – it’s an adventure novel – but usually yu do check *both* ignition sistems during the pre-flight checklist.

Start engine
switch to only magneto 1, watch the RPM drop a tad, both, RPM up
magneto 2, down again
both, up again,
