|That's not likely not true, but the blind landings require certain equipment, plane and crew certifications. There have been significant changes in the last few years. Zero visibility landings are more interesting once on the ground, with navigating around on the runway and taxiways when you can't see anything. It was not unusual to send a vehicle to drive out and leas the plane in. Then the hazard is taxiing on to an active runway, or collision with other objects on the ground. It's hard enough to keep those wingtips damage free.
An interesting item is private operators, not for hire can depart (with normal IFR clearances) in zero visibility. This could be a company owned plane with only company employees on board. But generally the ability to return to the same airport safely governs the go/no-go decision.

|When, I got out of flying 5 years ago, the blind landings were just starting to get approved, and there were relatively few planes crews approved. There have been significant improvements in the equipment available and quantity installed since then. I have to assume the air carriers (airlines) have taken up on this, and new planes delivered have the capability, many planes retrofitted, and crews trained and certified as part of their routine required (annual) training. And then to insurance carriers frequently have requirements that are beyond the FAA or other government agencies. I recently had a friend with a homebuilt aircraft install an EFIS (Electronic glass screen display) system in his plane. This is common place today, where 7 years ago, the cost was prohibitive.
Here's the standard ILS (Instrument landing system) approach procedure for our local airport showing 200' above, and 1/2 mile visibility as minimums
Here's the Catagory III ILS at Cleveland's airport showing no vertical restriction, but does have RVR 06 (Runway visual range = 600') which is saying the pilot needs a little (600' @ 120 mph) sight distance to navigate on the ground.
There might be better info, but this is what I found quickly.
