The 1st photo is of a (pressure) entry/exit hatch on an airliner. The Hatch has a “Red Strap” affixed to it. What is it’s pupose? What does it indicate?
2). The 2d photo depicts a hazard to aviation and civilians on the ground.
What is it
Thankfully ‘Blue Loo’ is getting rarer and rarer these days as most aircraft are tanked now.
I do remember a famous old Airbus 320 on the fleet that was known as the blue whale due to the flowing lines of the Blue Loo leak from the forward toilet that ran gracefully along the fuselage!
