Forget which bird, but flaps and gear controls were side by side and
not too different shaped. To prevent inadvertent retraction the rule
was you came to a full stop after clearing R/W and then looked down
and retracted the flaps. This pulling flaps up by feel while moving
was a invitation to disaster.


On the Fortress I was flying the gear and flap switches were both simply
toggle switches...with the gear switch being a "guarded" switch.
Procedure was at least two crew had to confirm your finger was on the
flap switch before activating.

Knowing the gear system I can't think of a reason/way for both to fail
together. Sad, but these things do happen.

Luckily they are tough old birds...the only limit to getting her in the
air will be money.

There is nothing - absolutely nothing - half so much worth doing
as simply messing around with airplanes.

Are there not "squat" switches that prevent the gear from being raised if
the plan is on the ground?

Originally no, but on the 909 a squat switch had been added. It sets
low on the left gear leg, soaked in Wright radial oil G and I wouldn't
trust it for a second.
