Best of luck to everyone.
I just got off the phone with the wife of my best friend. My best friend was scheduled to land at Heathrow today for a business meeting tomorrow. She hasn't yet heard from him (his plane was supposed to land about an hour ago), but I'm betting it's because things have probably slowed to a crawl at the airport, if they're moving at all.
My guess is they may still be on the tarmac, just sitting in the plane? And later, customs (he's inbound from the U.S.) will probably be snail's pace? Anyway, just hope he's o.k., and also wanted to wish everyone in the U.K. well. S'mon, hope your wife gets home without too much delay, and safely.
Take care, everyone,
