Jade Mallet, 8, was among 30 protestors at Downing Street

Thirty members of the Save Concorde Group protested with banners and placards outside Number 10.

Chairman Ross Mallet said: "We are not talking about passenger flights just now but six times a year at air shows."

The signatures were collected at air shows and over the internet from fans as far away as Australia and Peru.

The July 2000 Paris crash, the September 11 tragedy and the Iraq war all helped to make Concorde an uneconomical proposition.

The supersonic bird took its last commercial journey on October 23, 2003, 28 years after it first took off.

Mr Mallet, 37, from Burton-upon-Trent, Staffordshire, set up the group last year feeling cheated at never having had the chance to fly on her.
