The pair will then attempt to skydive into the other's plane.
Two skydivers are going to attempt a 'Plane Swap' on Monday.
Luke Aikins and Andy Farrington will try to jump out of one plane each - as they barrel towards the ground.
The pair will then attempt to skydive into the other's plane and land it within a minute.
Aikins and Farrington, both from Washington, will be hurtling towards the earth at 225 kilometres per hour.
