Awesome Japanese sewers and a REALLY big hole!

The suction above the hole resulted in several helicopter crashes, so all flight above the hole is prohibited now.

 

Why would there be suction above a simple 1.5 km wide hole?

 

 

I think its due to air flow/pressure. Cold air sinking into the hole as it is so cold there, may drag helicopters down without warning.

 

Almost like those very low air pressure 'mini super cells' that can cause planes to drop suddenly coming in to land.

 

Then again I'm probably wrong! :)

 

Edit: Amazing machines though!
