Swamp Thing:
'MRA4 on a test flight' - except it was an MR2 - in fact unless my eyes were wrong it was 2 x MR2s - XV248 taking off and XV246 going round the corner with the bomb doors open.
I have it on good authority that the BBC asked the MOD for footage of the MRA4 and were supplied with the pictures you rightly point out of MR2's .
Is this the fault of the BBC or is it just a MOD discrediting exercise .I leave you to make up your mnds.
