All US Flights are grounded in a repeat of 911. No take-offs but planes will be landed. "ATC communication issue" but rumours too of multiple bomb threats. International flights will be managed "on a case by case basis" but many in the air expected to be diverted to Canada.

Trump remains in Washington to keep briefed and in charge but should have flown to Florida.

Many flights have landed but not allowed to taxi to runway so passengers stuck on planes in Washinton. BA Flight 115 has landed at JFK.

?!

Could be leftover technical issues from the Microsoft outage. Then again, could be something else entirely.

• From BBC News.

• A passenger stuck on a plane at Los Angeles International Airport (LAX) says flights which have just landed are not being allowed to move from the tarmac to the gates.

  The passenger, who has travelled from Newark, tells the BBC's US partner CBS News that they're unable to taxi to the gate as another plane scheduled to take off is not being allowed to depart.

  Another passenger who just landed in Austin tells the broadcaster he and fellow travellers have been told they should "sit tight" as they're also unable to leave the plane.

• White House briefing soon but not confirmed if it will be Trump or someone else.

White House confirms it's an ATC communications failure and no threat has been made to US travel.

OMG, me reading this thread and knowing nothing near as dramatic was happening in real time
