Unfortunately it was a very British accent (dare I say English), although the aircraft was foreign registered.

Although the lowest altitude for holding at Alkin is 1800 ATC are unlikely to specify anything less than 2000
Devices the size of 747's are not catered for although in theory you could see 737's there. In reality most heavy metal is radar vectored by Thames Radar so they do not enter the hold. It is possible to come across exec. jet traffic training in the hold but they will normally also get a service from Thames.

That thought had also crossed my mind. Hate to think what he would do if he came across an airfield with an elevation higher than 2000 ft. (not that I can think of one in this country)
