No Stunts For Red Arrows At Farnborough
The Red Arrows will not perform stunts at the Farnborough Air Show for the first time in more than 50 years because of safety fears.
A decision was made to scrap the aerobatic displays following the Shoreham disaster last year, in which 11 people were killed.
The famous military planes will still carry out flypasts at the three-day show next month, but fans hoping to see loop-the-loops and barrel rolls at Britain's biggest air show will be disappointed after RAF bosses decided high-speed manoeuvres in such a built-up area were ``no longer appropriate''.
An RAF spokesman said: ``The high speed and dynamic nature of the traditional Red Arrows' display is no longer appropriate due to the large amounts of local housing, business areas and major transport links underneath the planned display area.''
The decision comes in the light of strict new safety regulations imposed by the Civil Aviation Authority (CAA) immediately after the crash at the Shoreham Air Show.
Eleven men died when a vintage Hawker Hunter jet exploded after ploughing into the A27 in Hampshire during a display.
