Low Flying is good fun. Thats it. There is no operational benefit from whazzing around at 50' (100').
and
The concept that we fly low to fly under radar beams is frankly tosh. Modern radars can see you manning up never mind low flying. Flying low puts you inside the threat band of many SA's and SAM's as well as placing you in a difficult and dangerous position.
To use your word - TOSH. In a helicopter, it's bloody vital. Terrain, trees,etc are the ultimate jammer. It's not rocket science (pun intended). I'm sure those that fly FJ would agree, but they can also fly high enough to evade stuff - we can't.
Yes, low flying happens to be fun, but it's also a vital and perishable skill. Ask anyone who's flown sausage side. Just why is it do you think that the Yanks have so many shot down?
