Abstract
We report ROSAT X-ray observations of two powerful radio galaxies. 3C 280 provides evidence for a mixture of unresolved and extended emissio n, with the latter produced by hot plasma of insufficient pressure to confine the radio lobes and insufficient density for a cooling flow to have begun. 3C 220.3 gives only an X-ray upper limit, but one consist ent with our interpretation of the X-ray emission from powerful radio- loud AGNs in terms of obscured and unobscured components.
