So, what is the situation regarding wrecks of allied aircraft?
If it is a USAAF machine that crashed in Britain will your MoD claim ownership? Or do you have to apply to the US Embassy? Or do the Yanks not give a damn?
And how about the exiled air forces? The Polish, Dutch and Norwegian governments actually paid for the equipment of their exiled air forces (I’m not sure about the Czechs and Free French). So if you recover the wreckage of a 303 Sqn Hurricane you should apply to the Polish MoD, not the UK one, I presume?

All military aircraft crash sites in the United Kingdom (UK), its territorial waters, or British aircraft in international waters, are controlled sites under the Protection of Military Remains Act 1986. It is an offence under this act to tamper with, damage, move or unearth any items at such sites, unless the Ministry of Defence has issued a licence authorizing such activity. As such, anyone wishing to recover a military aircraft, or excavate a military aircraft crash site in the UK is required to obtain a licence
