Heathrow Flow Control Problem
From 2030 UTC on the night of Monday 29th July, the Heathrow departure clearance controller began advising that all DVR departures were to expect indefinite delay. Subsequently all BPK and MID departures also went to indefinite delay. The quoted reason was that Maastrict control were accepting no traffic ex-LHR due to severe weather. Eventually aircraft were able to depart after 1 - 1 1/2 hour delays. Apart from one, admittedly severe, thunderstorm which passed over LHR at 2130 we saw no adverse weather over the whole of Europe.
Can any LATCC ATCO shed some light on the real reason for the chaos? I fail to see how one thunderstorm could have affected all continental departures for over an hour.
