Burning issue

According to you article 'Water works' (Interview, 8 May) the flame organ was 'an 18th century musical curiosity'. This implies the instrument has not been used for a century, and only its unusual principles are of interest today.

The late 20th century saw a triumphant renaissance for this instrument, which makes it outrageous and astonishing, rather than merely curious.

How to enter
Write a letter to The Engineer magazine and you could win a pair of tickets to one of bmi’s European destinations, courtesy of our friends at the airline.

Flexible and competitive
bmi asked 10,000 customers ‘what would make a great airline?’

The answer was clear: competitive fares, more choice and less time wasted at airports. So bmi acted, introducing a unique fare structure on domestic and European short-haul flights to and from London Heathrow. Thanks to three fare options — including premium economy, with benefits including lounge access and flexibility — you choose the services you want, depending on your business trip.

What’s more, bmi has streamlined the passenger process from the moment of buying the ticket, to your passage through the airport, to boarding the aircraft. You can book e-tickets online and then check in online at home, in your office, or even on the move.

Alternatively, there are self-check-in machines and priority check-in desks at the airport. You can even use bmi ‘web points’ to check in online at the airport, if that’s more convenient. All this means you can save valuable time from booking, right until your plane takes off.

The prize
Try the smart approach for yourself, courtesy of bmi. The winner of The Engineer’s Letter of the Month prize for April, as selected by the editor, will win a pair of tickets from London Heathrow to any destination on bmi’s European mainline network.
