Going off at a tangent here, I know....but....should those reindeer actually be on long final??
Assuming they are not all IFR approved - only Rudolph - and even he is unlikely to be FM immune....then they should not be operating at night in Billericay....and reindeer are not scheduled day time flyers when on the pressie dropping run.
This may suggest then, that they are operating at a "non towered" facility - at which the application of "long final" may be taken to be a straight in approach.
Not good.
