Talking of Dinky Toys, I had the Dinky 60c Percival Gull,... silly little bugger that I was,

Did someone post that or did you make it up?

No, actually we we were far from 'satisfied' with the Comet's problems, but most proud to be years ahead on the concept and then copied.

Whilst the Tu-104 continued to be used by Aeroflot throughout the 1960s and 1970s, the safety record of the aircraft was poor in comparison to subsequent jet airliners (16 of 96 aircraft were lost in accidents). The Tu-104 was unreliable, heavy, very unstable with poor control response, with an inclination to Dutch roll. Poor design aerodynamics of the wings resulted in a propensity to stall with little or no warning and a dangerous tendency to pitch-up violently before stalling and entering an irrecoverable dive. Due to the fear of inadvertent stalls aircrew would fly approaches above the recommended approach speed, landing at 270–300 km/h (170–190 mph), nearly 50 km/h (31 mph) faster. At least two accidents were attributed to the pitch-up phenomenon, prompting changes to the design of the aircraft and operating procedures, but the problem remained. Aeroflot retired the Tu-104 from civil service in March 1979 following a fatal accident at Moscow, but several aircraft were transferred to the Soviet military, which used them as staff transports and to train cosmonauts in zero gravity. After a military Tu-104 crash in February 1981 killed 52 people (17 were senior army and naval staff), the type was permanently removed from service. The last flight of the Tu-104 was a ferry flight to Ulyanovsk Aircraft Museum in 1986.

Whilst the Tu-104 continued to be used by Aeroflot throughout the 1960s and 1970s, the safety record of the aircraft was poor in comparison to subsequent jet airliners (16 of 96 aircraft were lost in accidents).

The Comet was remarkably successful until its inherent design flaw resulted in those accidents.

Compared to the Comet where only 26 were lost in accidents.

"The Professor's parachute invention was remarkably successful until he hit the ground."

One would have to analyse the number of hours flown and various other statistical factors, such as mode of operation etc. to make any meaningful safety comparison between the two aircraft.

That did not stop you saying the Tu-104 safety record was poor.

but it too was not without its flaws..

Looks like a lively day at EMA

The flight operated safely into EMA and no action was required from airport staff.'
