Trying washing one of these!
How about a Huey? Or an Osprey.
Here’s how they do it:
Keeping those Super Hercules clean is a 1½-daylong job. Starting in the early morning hours, mid-shift airmen prepare the massive aircraft for its cleanup. The maintainers responsible for prepping the birds said safety is their first priority.
They lower the wing flaps, remove access panels and disconnect the batteries, among other precautions.
“We have to deactivate certain systems to prevent shock and crush hazards to make the aircraft safe to wash,” Staff Sgt. Alexander Young said.
And, of course, the newbies get to do it. But, in Japan, they use contractors.
