#SpaceX is in the process of removing the final leg from the booster. Curious as to what the wind speed criteria is to move the booster? The Port has white caps!
They just removed the strut from the last landing leg. #SpaceX
They just removed the last landing leg from the #Falcon9. I think it’s to windy for them to move the booster today. #SpaceX #SpaceCoast @PortCanaveral
The CBI truck backed up to the #Falcon9 and connected into the rear. They must be draining something before moving to the transporter. #SpaceX
