HC Deb 11 March 1968 vol 760 c236W
Mr. Hugh Jenkins

asked the Minister of Technology how will the sonic boom of Concorde compare with that of the Lightning fighters.

Mr. Fowler

The intensity of the boom of each of these aircraft will vary with the height at which it is flying and its flight attitude and with the load carried. The differences in pressure wave forms will make a Lightning boom sound sharper than a boom of the same intensity caused by Concorde.
