Hi Savoia,
Mnay thanks for the detailed info and pic of NASA NH-53A, very much appreciated and here's my contribution. The guys out of Sigonella were very kind to bring their MH-53E Sea Dragon to Mildenhall 1995 Air Fete and I think it was the first time the Navy brought thier MH-53E to airshow in UK. As with Bush's visit several years ago, the HC4 when it was at Siognella, brought over their Sea Dragons to support his visit where they were sighted at Newcastle and other airports in the UK. Plus a visit in 2004 to RAF Northolt to support a delegation of congressmen and senators visiting the UK. I sighted a pair of these Sea Dragons over the Cambs countryside from my office on an airfield where I previously worked. By coincidence it turns out my one of my best mates in the RAF who was based at Northolt was on board said pair accompanying the US delegation!
Anyhow please find my scans on here (didnt enter the digital age till nearly a decade later from this!!!!
)
Cheers
