BA206... Delayed incoming and now blown starter motor
Sitting on the tarmac at MIA having pulled away from the stand 15 minutes ago (almost 4 hours late due to a technical issue with the aircraft flying the inbound which had to be replaced and so was late coming in to MIA).... And now the starter motor to one of the engines has blown resulting in lots of vehicles with flashing lights surrounding the left side 😳😳. Apparently can cause a spark hence the appearance of the cavalry.
Pulling back to the stand. Could be a late one...
Cue: discussion on knackered old 747s that need to be replaced (but I still like them)

Letter already sitting in my inbox using Which's very handy online EU261 comp letter writer/calculator 👍👍 ...€600 will come in very handy (unless of course BA argues exceptional circumstances).

Bleed air Jet engines, don't actually have 'starter motors' as such. To start them they need need air pressure (bleed air) to spin the engine, provided by the APU (if the APU is dead, it's not uncommon and doesn't ground an aircraft, then they need a ground unit, basically a trailer with an engine to supply high pressure air to the aircraft to do the same thing), once the engine is spinning, fuel is introduced and the igniters (spark plugs for a jet engine) start the combustion process/engine kicks into life.
787's uses electricity to spin up the engine (from the APU normally, but it could be ground power as APU's do pack up) to do the same as it doesn't have bleed air, so it uses the engine generators on the engines to spin up the engine to start them up.

Serious question - why, on a daily basis, is there always at least one thread dedicated to a specific flight, almost always BA, UA, AA, or DL (I'm sure others get thrown in for good measure) about delays etc? I mean, my Yakutsk-Moscow flight last weekend was delayed by almost 6 hours sans explanation yet I never felt a need to make a thread about it. 
Just curious as all.

I find such posts interesting and informative ie reason for delay, how it’s handled, EC261, etc.

I'm sure the Captain was dumbing it down for the passengers.....

In all seriousness, the on-time performance of BA’s 747 fleet is quite poor I would think (based purely on my anecdotal evidence). BA295 and return BA294 were both about four hours late departing yesterday due to issues with G-CIVR (colleague was on the flight). I’m now waiting for today’s BA295 which is also operated by G-CIVR so is of course running late because it’s still working off the delays accumulated yesterday.

Just curious as all.One of the best best things about the BA board I think is the willingness to help and there’s almost always something new that you learn everyday on here in the world of BA.

Theres also a lot of people on here with an incredible knowledge/info bank and they can often come up with more solutions /options for the OP that might have difficulty in accessing due to their location.
