Whilst BEags was perhaps a little strident in his questioning of tmmorris I'm afraid I agree with the sentiment. Querying what is perhaps something of a rare sight these days (Herc on 3, at a weekend) is completely reasonable. That one of the crew then took the time to talk through exactly what they were up to on the sortie was very good of him and should've been met with a "thank you and thanks for taking the time to explain".
Instead it's the standard PPL/spotter expert armed with an AIDU plate who decides to pick apart/challenge the professional. Seriously, if you think an aviation crime has been committed then ring Brize and pass them your dossier. If not, stick to enjoying your apples and make the most of the now extremely rare occasions military aircraft actually get seen in the skies over the UK.
