Definitely the Sud-Ouest Trident.
A fascinating mid-50s mixed-power fighter project. Wingtip turbojets for cruise, plus a multi-chamber rocket in the rear fuselage for take-off and hight speed interception.
Not much like the Bristol T.188 research aircraft which had a scaled-down Avro 730 wing. The T.188 had 2 of the useless Gyron Junior engines at mid-span, not at the wing tips. Rather an inefficient design, it had an endurance of about 25 minutes.... But I remember seeing the first take-off on TV when I was suffering from 'flu.
