There seems to be a trend to have experienced three go-arounds... and here are my three...
- Dan Air 1-11 at LGW
- Atlas Blue 737 at LGW
- Malaysian AL 747 at LHR
Only once was any explanation given and that was the Dan Air one (another a/c hadn't cleared the runway). It is a bit disconcerting, but let's face it, happens all the time.
