or does this type of thing not warrent comments
You are correct, it actually doesn't. On the Airbus we have surges and stalls more often than you might think. But most of the times there are no indications to the pax as they don't always make loud bangs/flashes/flames.
The bangs suggest something like a compressor stall, certainly a reason to reject takeoff.
Not correct. A bang could be anything, bird hitting leading edge, a toilet door slamming shut, wheel burst, aliens, etc etc. none of which you would high speed reject for. A lot of surges/stalls will auto recover and thus a high speed reject could give you more problems than continuing. Remember we are normally sitting quite a long way from the engines, so can't hear as well as if you are sitting over the wing. One single bang would probs not be enough for me to close the thrust levers.
