If it can take off vertically, even if that means a reduction in payload or range.....and then does it's job and to return and land vertically, what more can you say! :dance:

Yes, but the P1127 was nothing like the Harrier in terms of capability. In fact my ex-father in law (who was at Wittering when they first Harriers arrived, specialist in bang seats at that point) always says he can remember that the first GR1s struggled to get from one side of Wittering to the other.Garry Russell wrote:The Harrier went to war and was a great success.......seems like a pretty useful load to me!![]()

Well, the operational debut of the Corsair was with VMF-124, February 1943. By that time, the Spitfire IX had been in service for eight months and was a genuine 400 mph+ aeroplane. Incidentally, the Bf-109G also exceeded 400 mph in level flight, and entered service in late 1942.Chris Trott wrote:Sorry, meant FIGHTER. Any previous excession of 400 MPH was by experimental aircraft.Kevin wrote: - Supermarine S6B, ratified World Air Speed Record, 407 mph, in 1931!!!!
Actually, the Corsair's COMBAT debut was with VMF-124 in 1943. The OPERATIONAL debut (i.e. first squadron to reach Initial Operational Capability) was VF-17 which completed Carrier Qualifications and was declared Operationally Ready in late September 1942. However, the XF4U-1 (the production prototype) exceeded 400 MPH in level flight on 1 October 1940. This aircraft was fully equipped with weapons and armor, however Navy acquisition had not yet caught up with the War yet and aircraft still underwent relatively protracted development programs prior to introduction into service. Full production began in June 1941 with first deliveries occuring in June 1942.Kevin wrote:Well, the operational debut of the Corsair was with VMF-124, February 1943.

According to Jane's and Wikipedia, 0.69:1 is the "official" T-W ratio for the Lightning.TobyV wrote:Whats the thrust to weight ratio of a Lightning then... IIRC that can climb at 89 degrees and that angle the contribution of lift force in the direction opposite to the gravtational force on the aircraft must be negligible :think:
Actually chris he did predict one of them, Douglas and McDonnell Douglas are the same company.Chris Trott wrote:Well, ye'd be wrong on all 3 counts. In no particular order:VEGAS wrote:Wonder what Mr Trott's selection will be?
No let me guess..
1. Boeing ...........?

3) McDonnell Douglas F-15 Eagle
As were the engines on the F-15, the aircraft gained almost 8,000 pounds of additional thrust when the F-15As were put through the SLEP program and equipped with the F100-PW-220E (F100-PW-100 modified to the 220 "Equivalent") engines with no appreciable gain in weight. The F-15C was delivered with the F100-PW-220, and then has subsequently been upgraded with the F100-PW-229 that powers the F-15E and that gained the aircraft almost 10,000 additional pounds of thrust, again for almost no gain in overall weight.TobyV wrote:...the engines were upgraded a couple of times and the Sea Harrier and especially the AV8B/GR5/GR7/GR9 perform much better.
