By all means come into engineering just don't choose BA.
BA engineering is in turmoil at the moment with severe downsizing in progress and a generally demoralised workforce.
The place was great 10 years ago but things have most definately changed. Another 10 years will probably see most of BA's engineering outsourced (if it takes that long).
Wherever you go you won't be hated for your aspirations - just make sure you see them through!
